Epidemiological attribution of knee and ankle injuries in firefighters.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
This study aimed to evaluate the main factors of knee and ankle injuries among Chinese firefighters, focusing on the role of training arrangements, training conditions, and knowledge of training injuries. A questionnaire survey was conducted among 963 firefighters to collect data on training content, duration, load, protective equipment, rehabilitation measures and fatigue after training. Multiple regression analysis was used to explore the relationship between each factor and knee and ankle injuries. Logistic regression analysis revealed that training load parameter (A2) significantly reduced knee injury risk (OR = 0.784,95% CI = 0.642-0.958, p < 0.05), while personal protective equipment (B4) also showed a significant negative association (OR = 0.816,95% CI = 0.679-0.982, p < 0.05). Rehabilitation measures (C4) demonstrated marked protective effects against both knee (OR = 0.846,95% CI = 0.723-0.990, p < 0.05) and ankle injuries (OR = 0.697,95% CI = 0.606-0.802, p < 0.01). Conversely, post-training fatigue or discomfort (A6) was associated with increased ankle injury risk (OR = 1.251,95% CI = 1.119-1.398, p < 0.01). Likelihood ratio tests confirmed statistically significant models for knee (χ²=65.580, df = 15, p < 0.001) and ankle injuries (χ²=79.663, df = 15, p < 0.001), with ROC curves showing AUC values of 0.71 (95% CI = 0.67-0.75) and 0.75 (95% CI = 0.71-0.79) respectively, indicating excellent predictive performance.This study shows that training load parameters, personal protective equipment, rehabilitation measures and fatigue or discomfort factors after training play a significant role in the occurrence of knee and ankle injuries. Based on this, the study proposed a two-stage injury occurrence analysis and three-level intervention method to reduce training injuries based on data analysis of firefighters'knee and ankle joint injuries, including "training load monitoring-dynamic protection adaptation-accurate rehabilitation intervention".
