Injury and Illness Prevalence and Incidence in Swedish Olympic Athletes: A 3-year Prospective Cohort Study.
Article in Sports medicine - open, 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
backgroundOlympic athletes experience a high burden of health problems, and health surveillance is fundamental for understanding and preventing injuries, illnesses, and pain. Most surveillance data on Olympic athletes have focused on the Olympic Games, with limited data on injury, illness, and pain patterns outside the Games period.
objectivesThe primary aim of this study was to describe the prevalence, incidence, burden, and patterns of injury and illness, and pain prevalence, among Swedish Olympic athletes over three consecutive years.
methodsWe conducted prospective weekly health surveillance (April 2022-March 2025) of 225 elite Olympic athletes (51% males; median age 25 years). Health problems were reported using the Oslo Sports Trauma Research Center Questionnaire on Health Problems and diagnosed by the athletes' medical staff.
resultsA total of 1441 new health problems were reported (517 injuries, 924 illnesses), with a weekly prevalence of 23.6% (injuries 15.0%; illnesses 9.1%) and an incidence of 4.6 health problems/athlete/year (injuries 1.5; illnesses 3.1). Athletes lost on average 22 training/competition days annually (injuries 8 days; illnesses 14 days). Injury prevalence was similar between sexes and competitive seasons, with the knee (16%), lumbosacral region (14%), and shoulder (10%) being most affected. Illness prevalence was higher in females than in males (11.4% vs 6.9%; prevalence rate ratio (PRR) 1.6, 95% CI 1.4-2.0) and in winter compared with summer sports (11.4% vs 7.9%; PRR 1.4, 95% CI 1.2-1.7). Respiratory illness comprised 78% of cases. Weekly pain prevalence was 44%, with 65% of pain reports occurring without a concurrent reported health problem.
conclusionsOne in four Swedish Olympic athletes reported a health problem in an average week, with 4.6 new health problems and 22 time-loss days per athlete per year. Injury and illness patterns varied between subgroups, emphasising the need for targeted prevention strategies to reduce injury and illness burden in Olympic athletes.
