Impact of Body Mass Index on the Accuracy of Physical Examination and MRI of the Shoulder.
Article in Orthopaedic journal of sports medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe physical examination of overweight patients can require specific adaptations. Orthopaedic literature on the impact of body mass index (BMI) on the physical examination of the shoulder is virtually nonexistent. PURPOSE: To assess whether BMI affects the sensitivity and specificity of common shoulder tests, using arthroscopy as a gold standard. We also examined the effects of BMI on the sensitivity and specificity of magnetic resonance imaging (MRI) of the shoulder for reference. STUDY
designCohort study (diagnosis); Level of evidence, 2.
methodsWe analyzed the data of 116 consecutive patients who underwent shoulder arthroscopy for the treatment of rotator cuff tears, Bankart lesions, and superior labral anterior-posterior (SLAP) lesions. Preoperative BMI, physical examination of the shoulder findings, and MRI findings were extracted. Contingency tables and receiver operating characteristic curves were used to evaluate the sensitivity and specificity of provocative tests of the shoulder and MRI as well as their relationship to BMI.
resultsThe sensitivity and specificity of the Jobe supraspinatus test were 77.8% and 72.7% in patients with BMI ≤25, 82.6% and 70.6% in those with 25 < BMI ≤ 30, and 81.3% and 55.6% in those with BMI >30, respectively (
conclusionCounterintuitively, tests for shoulder instability had greater specificity in overweight patients and should be encouraged, particularly in obese patients, in whom the specificity of shoulder MRI for the detection of a Bankart lesion is lower. The Jobe test was more sensitive but less specific in overweight patients. These findings may assist care providers in improving the interpretation of the shoulder examination of overweight patients and consequently lead to better treatment-related decisions.
