A Odds ratios and 95% Confidence intervals for the impacts of the fixed effects of the model on knowledge scores. Variables marked with * are statistically significant (p < 0.05; see Table 2). The reference category for age is 20–25 years. The reference category for paediatric experience is 6–11 months and the reference category for sepsis care is weekly. B Estimated unadjusted random intercept and 95% CI per hospital site. Hospitals (1–14) have been sorted by size of estimated odds of correct response. The red solid vertical line indicates the population estimated intercept. C Adjusted random intercept and 95% CI per hospital site. Hospitals (1–14) have been sorted by size of estimated odds of correct response. The red solid vertical line indicates the population estimated intercept. Panel C shows the variation between hospitals after adjusting for fixed effects including factors, sepsis nurse funding and years of paediatric experience
