Adjusted odds ratio of the risk of pneumonia according to the microorganisms detected in nasopharyngeal samples, the Global Approach for Biological Research, Infectious diseases and Epidemics in Low-Income Countries (GABRIEL) Network, 2010 through 2014. aOR: adjusted odds ratio. The white diamonds represent adjusted odds ratio of pneumonia for a viral detection, with 95% CI. The black squares represent adjusted odds ratio of pneumonia for a co-detection of Streptococcus pneumoniae + virus, with 95% CI. All aOR are adjusted for gender, age, other microorganisms detected, and time period (year), with study center as the random effect.
