1 · What the graph read from 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.

2 · The registry

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

Background: Various intrinsic and extrinsic factors have been reported for rotator cuff tears (RCTs). This study aimed to assess the relationship between preoperative body composition parameters and postoperative clinical score in patients who underwent surgery for RCT. Methods: The participants in this study were 42 patients (42 shoulders; 33 men, 9 women) who underwent preoperative measurement of body composition and were then evaluated 1 year after surgical rotator cuff repair. Mean age at the time of examination was 61 years. Clinical outcomes were quantified using the Constant-Murley score, then patients were divided into an excellent group (Group E; Constant-Murley score ≥80) and a failure group (Group F; Constant-Murley score ≤79). Patient's background characteristics, preoperative physical findings, and body composition parameters were compared between Groups E and F. Results: Appendicular skeletal muscle mass (SMM) index of the upper limb on the affected side and phase angle were significantly higher in Group E (appendicular SMM index: Group E 0.50 ± 0.11 kg/m Conclusion: A relationship between RCT and whole-body condition has been reported but no reports have clarified the relationships between body composition parameters and clinical score for patients with RCTs. Relationships between preoperative body composition parameters and postoperative clinical score were investigated in patients with RCTs. The group with better preoperative body composition parameters showed significantly better postoperative clinical score. Moreover, the postoperative clinical score correlated positively with the appendicular SMM index and phase angle and negatively with extracellular water/total body water. These findings suggest that measuring body composition preoperatively may provide predictors of postoperative clinical score in patients with RCTs.
