School water, sanitation, and hygiene (WaSH) intervention to improve malnutrition, dehydration, health literacy, and handwashing: a cluster-randomised controlled trial in Metro Manila, Philippines

Table 4 Effect of intervention on children’s dehydration status

aIRR = adjusted incidence-rate ratio. aOR = adjusted odds ratio. CG = control group. CI = confidence interval. IG = intervention group. SES = socioeconomic status. U_sg = urine specific gravity
The p-value refers to the difference in intervention effect between the respective IG and the CG
*We defined dehydration according to U_sg. Any dehydration, U_sg ≥ 1.020. Mild dehydration, U_sg = 1.020. Moderate dehydration, U_sg = 1.025. Severe dehydration, U_sg = 1.030
**We used a multilevel mixed-effects Poisson regression model to estimate intervention effects, which can be interpreted as the aIRR of a desired follow-up outcome between the respective IG and the CG. The model included the respective IG, random intercept for the city, and robust standard errors. We adjusted for the child’s sex, age, and SES
***We used a multilevel mixed-effects logistic regression model to estimate intervention effects, which can be expressed as the aOR of change in prevalence of a desired follow-up outcome between the respective IG and CG. The model included the respective IG, random intercept for the city, and robust standard errors. We adjusted for the child’s sex, age, and SES
