Fig 1. Decision tree for GBS-related outcomes in children for an annual birth cohort in 183 countries comparing maternal vaccination against no vaccination (current standard of care).

Numbered boxes represent repeated model structure; however, the risks for some outcomes vary across repeated branches. EOGBS, early-onset GBS; GBS, Group B Streptococcus; iGBS, invasive GBS; LOGBS, late-onset GBS; NDI, neurodevelopmental impairment.
