Section in protocol (De‐Regil 2011)	Pre‐planned method proposed in protocol (De‐Regil 2011)	Reason for non‐use
Types of outcome measures	We will group outcome time points as follows: immediately post intervention, 1 to 5 months post intervention, and 6 to 12 months post intervention	We limited our analyses to the end of the intervention, as only 1 study reported on continued follow‐up post intervention, and only for the intervention arm. We have described this in the Characteristics of included studies tables
Measures of treatment effect	We will use the SMD to combine trials that measure the same outcome but use different units of measurement	Outcomes were reported in same units
Subgroup analysis and investigation of heterogeneity	For comparisons related to malaria‐endemic areas, we will conduct a subgroup analysis by treatment and prevention of malaria	No information was available for this review

SMD: standardised mean difference.
