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

objectiveCompare neuromuscular alterations of the ankle joint between individuals with chronic ankle instability (CAI) and copers who both experienced lateral ankle sprain (LAS) to examine the functional differences and guide rehabilitation strategies.

designSystematic review and meta-analysis. DATA SOURCE: A comprehensive search of PubMed, Web of Science, Embase, SPORTDiscus, and Scopus databases from inception to 1 December, 2025. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Observational studies and randomized controlled trials (RCTs) comparing neuromuscular function between copers and CAI patients were included.

resultsFifteen studies including 627 participants were analyzed. Meta-analysis showed CAI individuals exhibited delayed peroneus longus (PL) latency (g = -1.17, 95% CI: -1.62 to -0.73), and increased tibialis anterior (TA) and medial gastrocnemius (MG) activation (g = -0.49 and g = -0.35, respectively) compared to copers. No significant differences were observed in PL activation or co-contraction indices. Muscle morphology and performance showed inconsistent outcomes across studies, preventing meta-analysis.

conclusionFindings from meta-analyses indicate that copers exhibit different neuromuscular functional alterations compared to individuals with CAI. However, whether these alterations are compensations in response to LAS is still unclear. Clarifying this distinction may inform understanding of CAI development and generate hypotheses for future rehabilitation research.
