Study Groups
WWARN facilitates a number of collaborative Study Groups to undertake individual patient data meta-analyses to answer specific research questions about malaria treatments and antimalarial drug resistance. Gathering and combining data sets from multiple studies increases sample sizes, so that effects, including smaller effects, and effects on sub-populations can be identified with greater certainty. Working together and combining data from different regions and populations is improving our understanding of drug resistance and strengthening global efforts to control and eventually eliminate malaria.
