Number needed to treat (NNT) is the number of patients who must be treated with an intervention for a specific flow to prevent 1 bad outcome or result in 1 good issue. What is the reciprocal of the NNT? Utilize your mouse to highlight the answer:

Accented risk reduction, which is the proportion in the control group experiencing an outcome minus the proportion in the intervention group experiencing an event, is the reciprocal of the NNT.

See §xx.nine for a Glossary of Statistical Terms.—Laura King, MA, MFA, ELS

There are 5 instances of jargon in the following sentence. Tin you identify them all?

The patient's concrete exam findings were unremarkable and her labs were in the normal range, so she was released from the emergency room and prepped for surgery.

Highlight below for the answer:

The patient'south physical exam findings were unremarkable and her laboratory exam results were in the reference range, so she was released from the emergency section and prepared for surgery.

Words and phrases that can exist understood in conversation simply are vague, confusing, or depersonalizing are generally inappropriate in formal scientific writing. See §11.4 of the AMA Transmission of Style for a listing of jargon.—Laura King, ELS

A scientist develops data while working at Harvard Academy. She and so moves to Stanford University, where she publishes an article using the original information in JAMA. Who owns the data?

Use your mouse to highlight the answer: Harvard Academy

In scientific research, 3 main arenas exist for ownership of data: the government, the commercial sector, and academic or private institutions or foundations. Although an infrequent occurrence, when data are developed by a scientist without a relationship to a government bureau, a commercial entity, or an academic institution, the data are owned by that scientist. Whatever information produced by an role or employee of a regime agency in the course of his or her employment is owned past the government. Data produced by employees in the commercial sector (eg, a pharmaceutical, device, or biotechnology company, health insurance company, or for-profit hospital or managed care organization) are most frequently governed by the legal relationship between the employee and the commercial employer, granting all rights of information buying and control to the employer. According to guidelines established by Harvard University in 1988 and subsequently adopted past other US academic institutions, data developed by employees of bookish institutions are owned past the institutions (§5.6.i, Ownership and Command of Data, pp 179-183 in print).—Laura King, ELS

Which of the following sentences is correctly punctuated?

We conducted a randomized placebo-controlled trial.

OR

Nosotros conducted a randomized, placebo-controlled trial.

ANSWER:

We conducted a randomized placebo-controlled trial.

When fewer than 3 modifiers are used, avoid adding a comma if the modifiers and the noun are read every bit one entity, such as randomized placebo-controlled trial.—Laura Male monarch, ELS

Exercise yous know the divergence between the terms multivariable and multivariate? One term refers to multiple predictors (independent variables) for a single event (dependent variable), and the other term refers to 1 or more independent variables for multiple outcomes? Which is which?

Reply:

Multivariable refers to multiple predictors (contained variables) for a single effect (dependent variable). Multivariate refers to 1 or more contained variables for multiple outcomes. Therefore, analyses tin can be described as multivariable, to indicate the number of predictors, or as multivariate, to bespeak the type of outcome.—Laura Male monarch, ELS

Edit the following judgement for correct usage of anatomy terms:

The investigators examined catheter-induced lesions of the correct middle.

Highlight for the respond:
The investigators examined catheter-induced lesions of the right side of the middle.

Editor's Note: Authors frequently err in referring to anatomical regions or structures as the "right heart," "left chest," "left neck," and "right brain." Generally these terms tin be corrected by inserting a phrase such as "part of the" or "side of the" (§11.6, Beefcake, p 410 in impress).—Laura King, ELS

Edit the following sentence to eliminate jargon:

A 78-year-old adult female with a congenital heart and a history of high claret pressure level and heart set on was admitted to the hospital and prepped for surgery.

Highlight for the answer:

A 78-twelvemonth-old adult female with congenital centre affliction and a history of high claret pressure and myocardial infarction was admitted to the hospital and prepared for surgery.

Editor's Note: A heart is non congenital; the preferred terminology is congenital heart disease or congenital cardiac anomaly. Myocardial infarction, not heart set on, is the preferred term. Patients are prepared, not prepped, for surgery (§11.4, Jargon, pp 408-410 in print). Some of these terms may be acceptable for certain types of writing; peer-reviewed medical journals generally avoid them.—Laura King, ELS

Correct the grammar error in the following sentence:

We performed a quantitative overview of randomized trials which tested β-blockers in myocardial infarction, centre failure, and hypertension.

Highlight for the answer:

We performed a quantitative overview of randomized trials that tested β-blockers in myocardial infarction, eye failure, and hypertension.

Incorrect use of relative pronoun (which vs that) (§vii.2.2, Relative Pronouns, pp 317-319 in print). That introduces a phrase that is essential to the meaning of the sentence, and which introduces a phrase that adds more information merely is not essential to the meaning. Which should always be preceded by a comma. Another instance: "He visited the new hospital, which had been built concluding year" is correct. Yet, if there were 2 hospitals and simply i had been built final year, the sentence would read, "He visited the new hospital that had been built terminal year."—Laura King, ELS

Do you know the difference between disk and disc? What about vision and visual acuity? Or conjunctival hyperemia and conjunctival injection? That's right, this month we're talking well-nigh ophthalmology!

The AMA Manual of Fashion has an informative department on ophthalmology terms (§15.13). The department defines terms unremarkably used in radiology literature and offers teaching on how to use these terms correctly. Some of the terms addressed in the department are fovea, macula, chapeau, and orbit, as well as several acuity terms.

Run across if you lot can identify the problem(southward) in the following sentence from this calendar month's quiz:

At initial presentation, her best-corrected visual acuity was xx/xxx in each eye. Five weeks after, while taking xl mg of prednisone, she reported no improvement in her vision, and her all-time-corrected visual acuity remained at 20/thirty OU.

Highlight for the answer:

At initial presentation, her best-corrected visual acuity was 20/30 OU. 5 weeks later, while taking 40 mg of prednisone, she reported no improvement in her vision, and her best-corrected visual acuity remained at xx/30 OU.

The abbreviations OD (correct eye), Os (left middle), and OU (each center) may be used without expansion only with numbers, eg, 20/25 OU, or descriptive assessments of acuity. Note that OU does not mean both eyes, although it is frequently used incorrectly to imply a vision measurement (eg, visual acuity or visual field) with both eyes at the same time (§15.thirteen, Ophthalmology Terms, pp 736-739 in impress).

That's just a glimpse of what nosotros have to offering in this month's quiz on ophthalmology terms. If you're a subscriber, cheque out the complete quiz at www.amamanualofstyle.com.—Laura Rex, MA, ELS
