Design outcomes

Primary

MeasureTime frame
Haemoglobin concentrations, obtained by finger prick testing using HemoCue 201+ point of-care diagnostics, measured during the baseline (October 2008) and during the evaluation survey, nine months after the start of the treatments (June 2009)

Secondary

MeasureTime frame
The secondary outcome variable of our study came from a standardised math test that we administered ourselves at baseline (October 2008) and nine months after the start of the treatments (June 2009). The math test was based on questions drawn from a pool of questions that were originally created for The Trends in International Mathematics and Science Study (TIMSS). Enumerators required students to finish the 29 question test in 30 minutes. No extra time was given.
