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
objectiveThe aim of this study is to evaluate the clinical and radiological factors affecting the development of recurrent shoulder dislocation in patients who have been followed up with conservative treatment after the traumatic primary anterior shoulder dislocation (TPASD), and to identify patient subgroups at high risk of recurrence.
methodsFifty-four patients (40 males and 14 females) aged 18-65 years who presented with first-time traumatic anterior shoulder dislocation and were treated conservatively were retrospectively evaluated. Patients with and without recurrent instability during a minimum follow-up of 12 months were compared regarding age, sex, affected side, Bankart lesion, bony Bankart lesion, greater tuberosity fracture, rotator cuff tear, Hill-Sachs lesion, Hill-Sachs lesion depth, glenoid version, and rotator interval width. Multivariable logistic regression analysis was performed to identify independent predictors of recurrent instability.
resultsThe recurrence rate was 46.3% after a minimum follow-up of 12 months. Univariate analysis demonstrated significant associations between recurrent instability and younger age, male sex, the presence of bony Bankart lesions, the presence and depth of Hill-Sachs lesions, and the absence of rotator cuff tears. No significant differences were observed regarding affected side, Bankart lesions, greater tuberosity fractures, glenoid version, or rotator interval width. In multivariable logistic regression analysis, the presence of a Hill-Sachs lesion remained an independent predictor of recurrent instability (OR 7.88, 95% CI 1.77-35.08, p = 0.007).
conclusionRecurrent instability following conservative treatment of first-time traumatic anterior shoulder dislocation is strongly associated with structural bone defects. Although younger age and male sex were associated with recurrence in univariate analyses, multivariable analysis identified the presence of a Hill-Sachs lesion as the strongest independent predictor of recurrent instability. Detailed radiological assessment may therefore facilitate risk stratification and treatment decision-making following TPASD.
