Description of intervention(s) / exposure
This was a single arm prospective study to evaluate the efficacy and safety of artemether-lumefantrine. Artemether-lumefantrine tablets (containing 20 mg artemether+ 120 mg lumefantrine in each tablet) was given two times daily for three days according to the recommended weight bands: 1 tablet to those weighing 5 to 14 kg; 2 tablets for 15 to 24 kg; 3 tablets for 25 to 34 kg and 4 tablets for equal or greater than 35 kg. The total target dose ranges were 5-24 mg/kg body weight (bw)of artemether and 29-144 mg/kg bw of lumefantrine. All treatments was given orally under direct supervision by the health worker and patients were followed up for 28 days.Tablets were crushed and added to water in spoon and given to the child.

Statistical methods / analysis
Data was double entered by two independent data clerks using WHO database Excel programme, Data was analysed by both Kaplan-Meier and per-protocol methods. Patients were censored or excluded from the analysis if they were withdrawn or lost to follow-up or PCR results were unclassifiable or if the results of PCR indicate that the failure is due to reinfection with P. falciparum or P. vivax.

The final analysis will include:
• a description of all patients screened and the distribution of reasons for non-inclusion in the study;
• a description of all the patients included in the study;
• the proportion of adverse events and serious adverse events in all the patients included in the study;
• Prevalence of mutations in k13 gene associated with artemisinin partial resistance.;
• the proportion of patients lost to follow-up or withdrawn, with 95% confidence intervals and a list of reasons for withdrawal;
• the cumulative incidence of success and failure rates at day 28, PCR-uncorrected and PCR-corrected; and
• the proportion of early treatment failure, late clinical failure, late parasitological failure and adequate clinical and parasitological response at day 28, with 95% confidence intervals, PCR-uncorrected and PCR-corrected

Summary
Brief summary
Efficacy and safety of artemether-lumefantrine for the treatment of uncomplicated P. falciparum malaria infections in patients 6 months and above in Yemen was evaluated. The treatment was given under direct supervision and clinical and parasitological parameters were monitored for 28 days to establish proportion of patients with PCR corrected treatment failure, frequency of adverse events and mutations in K13 gene on day 0 samples.
