  1. n: number of cases included in the analysis. aOR Adjusted Odds Ratio, NA Not applicable, NS p. value is statistically not significant
  2. *p. values in bold reflect the overall exposure and are derived from the likelihood ratio test. p. value for variables with multiple exposure level are reported from the Wald test
  3. Variable included in the models are child age, gender, area classification, sanitation facility type, child fever history in the last 2 weeks, child has health insurance, wealth quintiles, anaemia status of the mother, and child malaria infection. Only variables with statistically significant p. values in the final model are presented in this table
  4. The Good-ness-of-fit test (Hozmer and Lemeshow) for the adjusted Odds Ratios for the 6 months to < 2 years age group X2 = 1.847 (7 df, p. value 0.968), for the 2 to < 5 years group X2 = 2.027 (5 df, p. value 0.845), and for the overall (6 months to less than 5 years) X2 = 13.947 (8 df, p. value 0.083)
