Univariable analysis using Cox regression to find variables associated with time to recovery in 7–120 day old infants with probable serious bacterial infection.

TLC- Total leucocyte count, CRP- C-reactive protein, PCT-Procalcitonin
Hazard ratio <1 indicates slower recovery
aVariables included in multivariable Cox regression analysis because their P-values were <0.2.
b Axillary temperature >37.5°C
c ≥60 breaths per min for infants <2 months; ≥50 breaths per min for infants ≥2 months.
