Scapular muscle activation and co-activation following a fatigue task.
Article in Medical & biological engineering & computing, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers.
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
Scapular muscles precisely move the scapulothoracic articulation and if fatigued may contribute to pathology. Fatigue of serratus anterior may be a mechanism for shoulder pathology by altering scapula motions and requiring compensation by other shoulder muscles. A total of 28 asymptomatic subjects performed a task to fatigue the serratus anterior, while muscle activity was recorded from three muscles. Mean normalized activation levels and activation ratios were examined before and after the fatigue task during arm elevation and lowering. All muscles demonstrated meaningful declines in the median frequency of the electromyographic signal during the task. Following the task, only the upper trapezius had higher mean activation levels (mean difference 10.79% MVIC), while the serratus anterior/lower trapezius activation ratio was altered (mean difference -0.3). Higher mean upper trapezius activation may be compensatory for fatigue of other shoulder muscles and may reflect fiber type or central control mechanisms. Serratus anterior eccentric endurance training may be beneficial for the prevention of shoulder pathology.
