Oxygen-related clinical practice change among children (top) and neonates (bottom) admitted to 12 hospitals in southwest Nigeria. Pulse oximetry coverage and oxygen provision expressed as the proportion of all children/neonates unless otherwise specified. ‘Indication for oxygen’ is expressed as the proportion of those given oxygen who had SpO₂<90% or WHO emergency signs. Error bars showing 95% CIs. Note: the oxygen coverage to patients with hypoxaemia indicator is biased in the preintervention period due to extremely low pulse oximetry coverage.
