This risk might be anticipated based on the known cardiac toxicities of both products, possibly due to combined effects on QT interval, or by combined cardiotoxic effects more generally. Confidence intervals (CI) are used to assess the true difference in risk between 2 groups, and usually accompany ratio values such as odds ratios, hazard ratios and observed versus expected ratios. Approval is based in part on results from the randomized, double-blind, placebo-controlled. Mefloquine and other drugs known to lower the convulsive threshold: PLAQUENIL can lower .
