Effects of blood flow restriction training on patients with chronic ankle instability: a systematic review and meta-analysis.
Synthesis in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo systematically review the effects of blood flow restriction training (BFRT) on postural control and ankle function in patients with chronic ankle instability (CAI).
methodsWe systematically searched PubMed, Embase, The Cochrane Library, Web of Science, EBSCO, and Scopus databases up to February 2, 2025. This study was registered in PROSPERO (CRD42025642187). The search aimed to collect randomized controlled trials examining the effects of BFRT on patients with CAI. Four outcomes including Y balance test reach distance, Cumberland Ankle Instability Tool scores, ankle muscle strength, and ankle muscle activation were selected. Quality of the included studies was assessed using the Cochrane Risk of Bias Tool Version 1, and meta-analysis was performed with RevMan 5.3.
resultsA total of eight randomized controlled trials were included, involving 243 patients with CAI. Compared to the control group, BFRT significantly improved Y balance anterior reach distance (MD = 4.90, 95% CI: 1.73 to 8.08, P = 0.002), Cumberland Ankle Instability Tool scores (MD = 3.09, 95% CI: 1.59 to 4.59, P < 0.001), ankle dorsiflexor strength (SMD = 0.90, 95% CI: 0.03 to 1.77, P = 0.04), ankle plantar-flexor strength (SMD = 1.12, 95% CI: 0.20 to 2.04, P = 0.02), and tibialis anterior muscle activation (MD = 11.13, 95% CI: 4.12 to 18.14, P = 0.002).
conclusionCurrent evidence showed that BFRT significantly improved Y-balance anterior reach distance, CAIT scores, ankle dorsiflexor and plantarflexor strength, and tibialis anterior activation. These findings supported its effectiveness in improving postural control and ankle function in patients with CAI. However, some included studies are of low quality, requiring larger, high-quality studies for validation.
