Figure 1From: Haemoglobin and haematocrit: is the threefold conversion valid for assessing anaemia in malaria-endemic settings?Scatter-plots of difference against average of haemoglobin and haematocrit/3 for each study. Scatter-plots of difference against average of haemoglobin and haematocrit/3 for paired measurements from children aged 6–59 months. The line of best fit (red) indicates a trend towards greater differences at lower haemoglobin values. Both axes are in "grams of haemoglobin/dl".Back to article page
