Incidence of Respiratory Syncytial Virus-Associated Hospitalization Among Adults in Ontario, Canada, 2017-2019.
Article in The Journal of infectious diseases, 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
backgroundRespiratory syncytial virus (RSV) causes substantial morbidity and mortality among adults. Given recent RSV vaccine authorizations, data on groups at highest risk are needed to support vaccine program decision making.
methodsWe identified adults aged ≥ 18 years hospitalized with laboratory-confirmed RSV and hospitalizations with RSV-related diagnostic codes in Ontario, Canada (2017-2019). We calculated incidence of hospitalization with 95% confidence intervals (CIs) using Poisson regression stratified by demographic and clinical risk factors, and substratified by age. We reported secondary outcomes including the proportion of individuals with fatal outcomes.
resultsOver 2 respiratory virus seasons, we identified 3928 RSV-associated hospitalizations. Incidence increased steadily with age from 2.0 (95% CI, 1.8-2.3) per 100 000 for those aged 18-49 years to 43.7 (95% CI, 41.0-46.6) per 100 000 for those aged 70-79 years, with a sharp increase to 134.7 (95% CI, 128.6-141.1) per 100 000 for those aged ≥ 80 years. Incidence was higher for those with comorbidities, including chronic kidney disease (receiving dialysis) (494.7; 95% CI, 410.7-595.8) and transplant recipients (370.9; 95% CI, 318.0-432.6), as well as for those living in lower (22.4; 95% CI, 21.1-23.7) versus higher-income neighborhoods (11.8; 95% CI, 10.8-12.8). Among those hospitalized, 10.3% (n = 403) died within 30 days of admission, and 93.1% of deaths occurred in those aged ≥ 60 years. Of survivors, 44.6% of community-dwelling adults aged ≥ 60 years had functional decline requiring formal supports at discharge. DISCUSSION: We found a substantial burden of RSV among older adults, particularly among those with preexisting medical conditions and those of lower socioeconomic status. These results will inform equitable vaccine recommendations for adults.
