Diagnostic value of the hourglass biceps test for the detection of intra-articular long head of the biceps hypertrophy.
Article in JSES international, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundShoulder surgeons performing tenodesis note a great variability in morphology of the proximal biceps. The hourglass biceps test measures the integrity of the intra-articular biceps tendon. The hourglass maneuver (HM) is positive when there is a passive flexion deficit compared to the contralateral shoulder in a relaxed patient in the supine position. HYPOTHESIS: Preoperative HM is correlated with an increased width of the biceps portion resected during tenodesis.
methodsThis prospective study evaluated all patients (N = 58) who underwent biceps tenodesis between January and September 2019. Two groups of patients were compared: group 1 (n = 20) had a positive HM and group 2 had a negative HM (n = 38). The smallest (s) and largest (L) width of the tendon were measured intraoperatively, and the L/s ratio was calculated. The HM was then evaluated as a diagnostic test by creating a contingency table and determining the sensitivity and specificity of the test for different L/s ratios. A receiver operating characteristic curve was created and the area under the curve (AUC) was calculated.
resultsA nonsignificant difference was found between the mean largest biceps width in group 1 compared to group 2 (11.65 mm [range: 5-21] vs. 9.71 mm [range: 6-20], respectively;
conclusionPreoperative positivity of the HM is linked to the increased width of the biceps portion resected during tenodesis. The hourglass biceps test should be predictive of intraoperative hourglass biceps according to our definition.
