Statistics and data analysis The study employed a cross-sectional design to investigate the ‘presence or absence’ of RESTV infection in Philippine bats. A target sample size of 120 individuals per taxa was set, based on the averaged ZEBOV and MARV seroprevalence reported in Pourrut et al. [1], to allow negative findings to be interpreted as providing 95 % statistical confidence of absence of infection in the taxa at a design prevalence of 2.5 %. The findings are presented as descriptive summary statistics.
