Figure 1.
Distribution of children with acute diarrhea by available methods of measure of the weight (n = 293).
Pre-illness weight: measured within 8 days before the ED visit. Theoretical weight: predicted from the child’s individual growth chart. Post-illness weight: the first weight when two consecutive daily weight measurements differed by <1%, after diarrhea and vomiting had disappeared.
Figure 2.
Correlation between theoreti cal and post-illness weight, assessed by Pearson Correlation (n = 111).
Postillness weight = 0.978 x Theoretical weight (p<10−6).
Figure 3.
Agreement between theoretical and post-illness weight, analysed with a Bland-Altman plot, n = 111.
M: mean, SD: Standard Deviation. Mean difference, which is the best guess as to the “correct” result. 95% limits of agreement. When the agreement between two measures is high, the mean difference between these two measures is close to 0. The 95% limits of agreement permit visual judgement of how well two methods of measurement agree. The smaller the range between these two limits the better the agreement is.
