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
objectivesThe aim of this study was to evaluate the clinical effect of glenohumeral injection with triamcinolone acetonide for frozen shoulder and to identify the factors related to extent of range of motion (ROM) recovery. PATIENTS AND
methodsBetween July 2015 and May 2020, a total of 305 patients with primary frozen shoulder (147 males, 158 females; mean age: 55.8±4.3 years; range, 52 to 73 years) who underwent intra-articular glenohumeral injection of triamcinolone acetonide were retrospectively analyzed. The primary outcome measure was the range of changes in each aspect of ROM at six weeks after injection. The relationship between improvement and unresponsiveness to intra-articular injection for the treatment of frozen shoulder with various factors were evaluated. The analyzed factors were as follows: age, sex, body mass index (BMI), initial ROM before injection, symptom duration, hand dominance, smoking history, and the existence of underlying disease including diabetes mellitus, hypertension, coronary disease, thyroid disease, and hypercholesterolemia.
resultsThere were significant improvements in all aspects of ROM at six weeks after injection. The forward flexion (r=-0.346, p<0.001) and external rotation (r=-0.204, p=0.040) showed a negative correlation with BMI. Multivariate analysis revealed that BMI was the sole factor related to recovery of forward flexion (p=0.032) and external rotation (p=0.007) at six weeks post-injection.
conclusionIntra-articular injection of triamcinolone acetonide is an effective method for improving ROM in patients with frozen shoulder. Increased BMI showed adverse effects on ROM recovery.
