Table I.
Summary statistics for charts from the 48 sporozoite-induced and 61 trophozoite-induced infections with more than 14 days of observed preintervention patency. Values of magnitude variables are given as absolute numbers, per cubic millimeter densities (mm−3), or degrees Farenheit; values of timing variables (days) are given as relative to the first day of patency (day 1). If 2 or more prospective peaks of equal magnitude occurred in a chart, the timing is considered to correspond to the earliest. Separate sections refer to 66 charts in which gametocytes of both sexes were recorded (and days on which males and females were detected either simultaneously or alone) and 30 in which only male gametocytes were recorded (see Materials and Methods). Abbreviations: minimum, Min; maximum, Max; standard deviation, Std Dev; percent, % recorded, Rec; gametocytes, Gam; male, M; female, F.
