Epidemiology of injuries in junior karate athletes: incidence and patterns at the Iranian National Championships.
Article in BMC sports science, medicine & rehabilitation, 2026. 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
backgroundThe rise in youth karate competition participation correlates with elevated injury risk. This study investigated injury incidence and patterns among Iranian junior athletes at the 2023 National Karate Championships (Tehran, April-May 2023), the official selection event for the national team, considering differences by age, sex, weight, and bout characteristics.
methodsA prospective cohort design was employed, analyzing data from 1391 athletes across 1544 bouts. Injury data were systematically collected by qualified medical personnel using standardized forms. Injury incidence rates (IIRs) were rigorously calculated per 1000 athlete-exposures (AEs) and per 1000 min of exposure (MEs) to account for varying exposure durations.
resultsA total of 527 injuries were recorded during the competition. The overall IIR was determined to be 18.94 per 1000 AEs and 9.02 per 1000 MEs. The face was identified as the most commonly injured anatomical site, accounting for 46% of all injuries, while contusions were the most frequent injury type, comprising 48%. Athletes in the Under-21 (U21) male category exhibited the highest injury rates. Furthermore, more than half (52%) of all recorded injuries occurred within the first minute of a bout, and losing athletes sustained a disproportionately high 59% of the total injuries.
conclusionIn conclusion, this study identified a high injury incidence among Iranian junior karate athletes, with the face being the most commonly affected region and contusions the predominant injury type. Male and U21 athletes showed notably higher injury rates, particularly early in bouts and among those who lost. These findings highlight the need for targeted preventive strategies and serve as a national benchmark for future injury surveillance in youth karate.
