Clinical characteristics of patients with posterosuperior labral tear: a comparison with patients with other shoulder disorders.
Article in Journal of pain research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAmong the various causes of shoulder pain, the glenoid labral tear is likely to be overlooked due to its ambiguous symptoms, especially if clinicians do not have a prior suspicion, making it difficult to diagnose, unlike adhesive capsulitis or a rotator cuff tear. Therefore, the aim of this study was to evaluate the clinical features of posterosuperior (PS) labral tear.
methodsOf the patients who visited the clinic, the medical records of patients with shoulder pain who underwent shoulder magnetic resonance imaging or ultrasound after intra-articular injection (arthrosonography) were investigated retrospectively. Based on these criteria, a total of 120 patients with adhesive capsulitis, rotator cuff problem, or PS labral tear were included for analysis in this study.
resultsIn the physical examination, all patients with a PS labral tear were positive on the O'Brien test (13/13, 100%) and the external rotation (ER) test with the upper arm in the abduction position (abduction and ER [ABER] test) (13/13, 100%), but they were negative on other tests, such as the Hawkins-Kennedy (1/13, 7.69%) and Neer (0/13, 0.00%) tests. Except one patient, all patients with a PS labral tear were negative on the ER test with the upper arm in the neutral position (ER test) (1/13, 7.69%). In the clinical history, all patients with a PS labral tear had a characteristic episode of shoulder pain occurring in the excessive ABER posture.
conclusionIn patients with characteristic physical findings (no definite loss of motion of the shoulder joint, negative in an ER test, but positive in an ABER test and O'Brien test), and with a clinical history of PS labral tear (a history of pain occurring with the excessive ABER posture), clinicians need to have a suspicion of PS labral tear and to identify the PS labral tear using MRI or arthrosonography.
