Variance attributable to predictors in univariate and multivariate regression models for asymptomatic and subclinical influenza infection prevalence, by study characteristics, as determined through a systematic review and meta-analysis of 55 studies

Univariate model
Influenza type/subtype 0.1599 0.0345
Laboratory test used to detect influenza 0.0043 0.0546
Hemisphere where study was conducted 0.0001 0.0159
Continent where study was conducted 0.0045 0.0213
Decade when study was conducted
Multivariate model 0.1676† 0.1478‡

*Variance not reported because all the studies were from the same decade.
†Model adjusted for influenza type/subtype, laboratory test, and location (continent) of the study.
‡Model adjusted for influenza type/subtype, laboratory test, location (continent) of the study, and decade when the study was conducted.
