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: Reverse total shoulder arthroplasty (rTSA) and superior capsular reconstruction (SCR) have not been previously compared with respect to muscle strength recovery, which may be an important factor influencing activities of daily living. We aimed to elucidate functional recovery profiles based on muscle strength and range of motion (ROM) in patients undergoing rTSA or SCR using tensor fascia lata graft for irreparable rotator cuff tears. Methods: The rTSA and SCR groups comprised 20 and 22 patients, respectively, with a minimum follow-up of 2 years. Muscle strength (abduction, external rotation, and internal rotation) was evaluated using a handheld dynamometer (FET Manual Muscle Testing System, Nihon MEDIX, Japan). Strength on the affected side was compared with that on the unaffected side and between groups. Shoulder ROM was also assessed. Results: The SCR group showed lower abduction strength recovery than did the rTSA group (52% vs. 67%, Conclusion: While rTSA provides superior abduction strength recovery, SCR offers significantly greater ROM in flexion, abduction, and internal rotation. This distinction between ROM and muscle strength may provide clinically meaningful context for surgical decision-making.
