  1. a the estimate lies within the confidence interval when it is in five decimal digits
  2. b Model in Step I analysis comprises age, sex and nutritional status of child, maternal religion; in step II, only significant terms in step I, age as a quadratic term, interactions of nutritional status with maternal religion, with age as a linear term and as a quadratic term were added to step I model; and in step III, non-significant terms in Step II model were dropped beginning from a non-significant interaction between nutritional status and age as a quadratic term
  3. c Multivariable Poisson regression model was fitted; d Incident rate ratio, analogous to odds ratio, is obtained by exponentiating the coefficient in the Poisson model; e age of a child (in months); Age2, age squared
  4. f ‘Nutri, nutritional status of child’: severely acute malnourished, coded as 1, ‘non-malnourished’ coded as 0 is a reference
