Afternoon kick-off, evening kick-off, or night kick-off in the first German Bundesliga - A possible Injury risk factor?
Article in SICOT-J, 2024. 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
introductionThis retrospective cohort study aimed to evaluate the impact of kick-off time on the risk of injury for professional soccer players in the first German Bundesliga. It was hypothesized that late kick-off times would have a negative effect on muscle and ligament injuries to the ankle and knee.
methodsKick-off times and injury data were collected over 5 consecutive seasons (1530 matches; 2014-2019) from two media-based registries (transfermarkt.de
resultsA total of 1327 match injuries were recorded over 5 seasons in 510 different male elite soccer players. The injuries affected muscles in 32.1%, ankle ligaments in 7.8%, and knee ligaments in 5.6%. There was no significant difference in injury rates when comparing different kick-off time groups (p > 0.05), however, the mean of time attributed to muscle and ankle ligament injuries suffered in games with a late kick-off time was significantly longer (p < 0.05).
conclusionThis study shows that there is no significant (p > 0.05) association between three different kick-off time groups and injury risk in the first German Bundesliga. However, significant (p < 0.05) differences in the lay-off times attributed to muscle and ankle ligament injuries differed with different kick-off times assorted into the three groups. Reasons for this observation could be found in the circadian muscle rhythms and muscle fatigue.
