p value: comparison of An. gambiae s.l. allelic frequencies (F (R)) between the treated and control communes, by department and for all departments (Test used: Chi-square test)
SS: susceptible homozygous; RS: heterozygous (resistant and susceptible hybrid); RR: resistant homozygous; %: percentage; (n): number of specimens analysed
