Yate’s correction applied. Fisher’s exact test applied. WHO/NCHS classification: underweight = weight for age < −2 SD; stunting = height for age < −2 SD, while severe wasting = weight for height < −3 SD from the mean. The figures in parentheses are percentages of the total in each column. RR: respiratory rate, cpm: cycles per minute, and : axillary temperature. Kwashiorkor and Marasmic kwashiorkor.
