Correction: Derivation of the first clinical diagnostic models for dehydration severity in patients over five years with acute diarrhea

There are errors in Table 5. The reference levels for regression coefficients should be 0 instead of 1. The cutoff levels for vomiting in the left-most column should be 1–4, 5–9, and >9 instead of 1–5, 6–10, and >10.
