FIG. 1.

Relationship between treatment dose (in milligrams of S-P received per kilogram of body weight) and the probability of being parasitemic 7 days after treatment between April 1993 and April 1998. Error bars represent the upper 95% CI, corrected for multiple observations per child. Values above the error bars represent the relative risk (95% CI) of treatment failure, with the highest-dose group as the reference. The S-P dose used was based on age: 125 plus 6.25 mg (one-quarter of a tablet) in infants, and 250 plus 12.5 mg (one-half of a tablet) in 12- to 23-month-old children (17).
