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
A prospective case control investigation was conducted to assess corticomuscular coherence (CMC) under different balance conditions in order to identify alterations that may arise due to forward head posture (FHP). Sixty-four participants (between the ages of 18-25) were recruited for this study. Participants were free from any musculoskeletal symptoms and matched for relevant demographic variables. Participants were assessed for FHP using the craniovertebral angle (CVA) and separated into either the normal head posture (NHP) group by CVA > 50° or the FHP group by CVA < 50°. Participants were evaluated using the Biodex balance system while both EEG and EMG signals which were acquired simultaneously to investigate CMC. Balance was investigated under four conditions increasing in challenge: (1) standing with eyes open, (2) standing with eyes closed, (3) unstable standing with eyes open with the Biodex set on level 8, and (4) unstable standing with eyes closed with the Biodex at level 8. In addition to recording delta, beta, theta, alpha, and gamma waves, we calculated both peak and average coherence values from the CMC analysis. Statistically significant differences were identified for the FHP group vs. the NHP group for both peak (p < .001) and average CMC values (p < .001) and for the interaction of balance difficulty (stage 1 vs. stage 4), p < .01. Similarly, all brain waves (delta, beta, theta, alpha, and gamma) demonstrated statistically significant differences between the NHP and FHP groups (p < .001) and for increasing balance difficulty across the four stages, p < .05. This study demonstrates that FHP is associated with a significant elevation of CMC, a unique compensatory burden on the brain, particularly during physically challenging balance tasks.
