Populations at Risk for Severe or Complicated Rhinovirus Illness: A Systematic Review and Meta-Analysis.
Synthesis in Influenza and other respiratory viruses, 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
backgroundAlthough most rhinovirus infections are mild and subside quickly, vulnerable populations may experience severe illness. Identifying populations at risk for severe or complicated rhinovirus illness can strengthen the ongoing search for preventative and therapeutic treatments. This systematic review and meta-analysis aimed to summarize the populations at risk for the development of severe or complicated rhinovirus illness.
methodsWe searched CENTRAL, EMBASE, and MEDLINE in April 2024 for studies reporting risk factors for severe rhinovirus infection, defined as lower respiratory tract infection (LRTI), hospitalization, critical care unit (CCU) admission, mechanical ventilation, or death. We pooled odds ratios using random-effects meta-analysis, assessed risk of bias using the Newcastle-Ottawa Scale, and rated the certainty of evidence using the GRADE framework.
resultsFrom 29 observational studies (n = 13,185 participants), we analyzed 13 risk factor-outcome combinations. With high certainty, age < 1 year and premature birth are not associated with the risk of LRTI, and diabetes mellitus is not associated with mortality. With moderate certainty, any comorbidity and pulmonary comorbidity are probably associated with increased risk of LRTI, age > 18 years and malignancy are probably associated with increased risk of mortality, and malignancy is probably associated with an increased risk of CCU admission. Many risk factors lacked sufficient evidence for meta-analysis.
conclusionsIndividuals with comorbidities are at greater risk of severe rhinovirus illness. Our findings can inform clinical risk stratification and guide the development and targeted use of emerging therapies. Further comprehensive research is required to elucidate additional risk factors and strengthen the evidence.
