Table 1. The percentage (%) recapture, geometric mean of hourly mosquito landings, percentage protection, mean complete protection time (CPT) and odds ratio between MAÏA® repellent ointment, 20% DEET and absolute ethanol

From: Single blinded semi-field evaluation of MAÏA® topical repellent ointment compared to unformulated 20% DEET against Anopheles gambiae, Anopheles arabiensis and Aedes aegypti in Tanzania
