Viral acute respiratory illnesses in elite athletes: A 12-month controlled follow-up study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundViral acute respiratory illnesses (ARIs) are the most common acute illnesses in elite athletes. However, the occurrence, aetiology, and clinical manifestations of viral ARIs in athletes remain unclear.
methodsTwenty-four elite cross-country skiers and 22 elite orienteers were followed for 12 months. Thirty-two normally exercising, healthy young adults were recruited as controls. Occurrences of ARI symptoms were collected weekly with a digital questionnaire. Nasal swabs for respiratory viruses were collected at the onset of symptoms and once monthly when asymptomatic.
resultsA significantly higher incidence density (per person per year) of ARI during the 12-month follow-up period was detected in the skiers compared to the controls (mean (SD) 3.39 (2.13) vs. 2.11 (1.98), respectively, p = 0.037) whereas the differences between the skiers and orienteers (mean (SD) 2.39 (1.07)) and between the orienteers and controls did not reach statistical significance (p = 0.053 and 0.506, respectively). The COVID-19 pandemic prevention measures and lockdown dramatically eliminated the occurrence of ARIs in all study groups. ARI episodes were shorter and milder in the orienteers (not studied in the skiers) compared to the controls (p = 0.001 and p = 0.001). A combination of international flights and participation in a competition was associated with a significant risk of an ARI episode in the skiers (p = 0.048). Rhinoviruses (54.1%) and seasonal coronaviruses (21.6%) were the most common viruses detected in all study groups.
conclusionThe incidence of ARIs was higher among the skiers compared to the orienteers and the controls. However, ARI episodes were shorter and milder in the orienteers compared to the controls.
