Fig. 1From: Predicting mortality in sick African children: the FEAST Paediatric Emergency Triage (PET) ScorePlots of the relationship between haemoglobin and lactate and mortality estimated from the adjusted Cox regression model. a Contour plot of mortality risk by baseline haemoglobin and lactate estimated from Cox regression model. This shows in contrast to risk uniformly increasing with increasing lactate and uniformly decreasing with haemoglobin as might have been expected, we have observed increased risk (green to red) when haemoglobin is increasing and lactate is increasing relative to an average child enrolled who had a lactate of 5 mmol/L and a haemoglobin of 7 g/dL. b Scatter plot of observed baseline haemoglobin and lactate valuesBack to article page
