Flow chart with a summary of the articles included in this systematic review. Titles and abstracts were screened from 220 papers. Of these, 171 non-relevant articles were excluded because reported data on imported cases in non-endemic areas included febrile patients attending healthcare facilities, serologically tested convalescent individuals, reported non-human experimental data, were case-reports or presented any other exclusion criteria identifiable in their abstracts. A further six papers were found to be ineligible after reading the 49 full-text articles assessed for eligibility criteria (lacked relevant information on the variables of interest: ascertainment of malaria diagnosis, description of the serological method used, target population and representativeness of general population). Of the 49 potentially eligible papers, 20 were considered to be of poor quality (scored <70% when the critical appraisal tool was applied) and were therefore excluded
