Effect of knowledge of sulfadoxine-pyrimethamine (SP) as prophylaxis for malaria on its uptake for intermittent preventive treatment of malaria in pregnancy (IPTp): Application of inverse probability weighted regression adjustment (IPWRA) technique.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionMalaria still remains a global health issue. In response, the World Health Organisation has continuously recommended the use of Sulfadoxine-Pyrimethamine (SP) for Intermittent Preventive Treatment of Malaria in Pregnancy (IPTp) as a malaria preventive measure for the mother and fetus, which has been implemented by the Ugandan government. In collaboration with partners, the government has created awareness of using SP for IPTp (SP-IPTp) among women mainly through media. Studies have investigated the effect of a woman's education attainment on SP-IPTp. However, the effect of knowledge of SP as prophylaxis for malaria on SP-IPTp has not been studied. Notably, education does not necessarily have an effect on knowledge of SP for malaria prevention, and knowledge of SP as prophylaxis may not result in its significant uptake for IPTp. The purpose of this study, therefore, was to ensure baseline covariate balance and determine the effect of knowledge of SP as preventive chemotherapy on its uptake for IPTp.
methodsThe study utilised the Ugandan Malaria Indicator Survey dataset of 2018-19. Women aged 15-49 years who indicated their uptake status of SP during their last pregnancy formed the sample of this study. The inverse Probability Weighted Regression Adjustment technique was applied to assess the study objective.
resultsThe findings revealed a positive and significant effect of knowledge of SP as malaria prophylaxis on its uptake for IPTp (Average Treatment Effect of the Treated or ATET = 0.163; 95% CI = 0.138-0.188).
conclusionEnsuring covariate balance while applying IPWRA resulted in more precise estimates of treatment effects. Programmes and policies that create awareness of using SP as malaria prophylaxis may serve as effective interventions towards SP-IPTp in Uganda.
