Antenatal care surveillance for monitoring malaria prevalence and intervention coverage: a multicountry analysis.

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
Estimates of malaria prevalence and intervention coverage in Africa are primarily based on nationally representative household (HH) surveys. However, the expense and infrequency limit the utility of HH surveys for operational action by malaria programmes. We assessed whether data collected during first antenatal care (ANC1) visits, consisting of data on malaria prevalence using rapid diagnostic tests, ownership of insecticide-treated nets (ITNs) and treatment-seeking for children with fever, could provide relevant data to guide decision-makers. Malaria prevalence among ANC1 attendees in select areas of six countries (Benin, Burkina Faso, Mozambique, Nigeria, Tanzania and Zambia) was compared with prevalence data among children under 5 and school-aged children from cross-sectional HH surveys in the same areas. To examine the relationship between prevalence among ANC1 attendees and children, we fitted a linear trend to the log-OR of the risk of testing positive. The predictive performance of the model was assessed by leave-one-out cross-validation (LOOCV). District-level ANC1 prevalence and prevalence among children are correlated (Spearman's rank correlation, r=0.79, 95% CI=0.65 to 0.88, p<0.001) and ANC1 prevalence is predictive of prevalence among children (LOOCV mean absolute error=6.5%). To understand whether data on ITN ownership collected at ANC1 are representative of ownership in the underlying communities, we assessed the district-level proportion of HH ownership in five countries (Benin, Burkina Faso, Mozambique, Nigeria and Zambia) and fitted an ordinal regression model to the ranking of ownership by district. Reported rates of treatment-seeking for children under 5 with fever, testing for malaria and treatment for the HH and ANC1 settings were compared. Estimates of malaria prevalence and ITN coverage derived from ANC1 attendees correlate well with HH survey estimates and may be useful in monitoring malaria prevalence and prevention efforts. In contrast, data on treatment-seeking does not appear useful.
