†Prodromic period distribution quartiles (Q25–Q75). Odds ratio for vomiting between survivors and non-survivors was 0.06 (95% confidence interval (CI) 0–1.81) and for edema was 0.14 (95% CI 0.01–2.81). Odds ratio could not be calculated for the presence of oliguria and fever because there were insufficient patients to perform this calculation.
