The effect of quarterly albendazole during childhood on asymptomatic malaria parasitaemia, haemoglobin and growth.

Malaria parasitaemia results were missing for 39, 53, 52 and 38 children at ages 2, 3, 4 and 5 years, respectively; haemoglobin results were missing for 17, 28, 658b and 13 children at ages 2, 3, 4 and 5 years, respectively; weight-for-age z-scores were missing for 2, 0, 1 and 4 children at ages 2, 3, 4 and 5 years, respectively; height-for-age z-scores were missing for 12, 2, 9 and 12 children at ages 2, 3, 4 and 5 years, respectively; weight-for-height z-scores were missing for 16, 4, 11 and 184c children at ages 2, 3, 4 and 5 years, respectively.aThe effect of quarterly albendazole on asymptomatic malaria parasitaemia changed with time (interaction p = 0.02), therefore the overall effect of the intervention on this outcome is not presented.bHaemoglobin was not measured for four-year olds from 22nd January 2009 onwards due to budget constraints.cWeight-for-height z-scores could not be calculated using WHO Anthro software for children who were aged >5 years and 1 month.
