<p>Fig. A: Discussion of study plans at the Field Unit. Fig. B: Researchers visit a study village to review lymphatic filariasis control. Table A: Microfilaria prevalence (MfP) by village and year. Table B: Antigen prevalence (AgP) by village and year. Table C: Average prevalence of MfP and AgP in base year (2010) and final year (2013) by condition. Text A: Sensitivity analysis. Table D: Incremental costs and change in MfP prevalence. Table E: Incremental percentage reduction in MfP by condition compared to MDA. Table F: Sensitivity analysis of incremental cost-effectiveness ratios of vector control conditions (dollars per person per year per percentage point change in MfP prevalence). Table G: Prevalence of lymphatic filariasis globally. In India, and in Tamil Nadu, 1990–2021. Fig. C: Distributions of base and final years’ LF prevalence by condition.</p> <p>(DOCX)</p>
