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

backgroundExercise is a first-line treatment for rotator cuff (RC) tendinopathy, but responses are variable. Defining mechanisms underlying patient improvement is necessary. This study investigated the relationship between neuromuscular factors-specifically peak force, rate of force development (RFD), and muscle activation onset-and patient-reported disability outcomes during an 8-week resistance exercise program.

methods51 participants with RC tendinopathy underwent assessments of peak force, RFD, and EMG muscle activation onset at baseline, 2, 4, and 8 weeks. Penn Shoulder Score measured patient-reported disability. Linear mixed-effects models assessed changes over time and the association between variables.

resultsPenn scores improved from baseline through weeks 2, 4, and 8. RFD increased in external rotation and abduction and peak force in external rotation and earlier EMG onset of deltoid and RC muscles. Baseline Penn score, increase in isometric abduction peak force from week 0 to week 2 and from week 2 to week 4 were associated with improved disability outcomes after controlling for pain during the task.

conclusionSeveral force and muscle activation variables changed after the exercise intervention, but only abduction peak force was related to patient-reported disability outcomes. This may offer added insight into individual recovery mechanisms beyond patient-reported outcomes alone.
