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
Placenta-related complications contribute substantially to maternal and perinatal mortality globally, with the greatest burden in low- and middle-income countries (LMICs). However, the potential influence of inadequate household water, sanitation and hygiene (WASH) on these outcomes remains poorly characterised. We investigated associations between household WASH conditions and selected placenta-related complications, including pre-eclampsia, small-for-gestational-age (SGA) and stillbirth, in The Gambia, Kenya and Mozambique. This secondary analysis was nested within PRECISE (PREgnancy Care Integrating Translational Science, Everywhere), a prospective observational cohort of 5,745 unselected pregnant women. Multivariable modified Poisson regression with robust standard errors was used to assess associations between household WASH exposures and pre-eclampsia, SGA or stillbirth. Missing exposure and covariate data were low (<5%) and handled using multiple imputation. Compared with water piped into the dwelling or plot, other improved water sources (adjusted relative risk [aRR] 1.18, 95% confidence interval [CI] 1.07-1.31, p = 0.002) and unimproved water sources (aRR 1.23, 95% CI 1.00-1.50, p = 0.049) were associated with a higher risk of any selected placenta-related complication. Unimproved sanitation facilities, compared with improved facilities, were also associated with increased risk (aRR 1.15, 95% CI 1.02-1.30, p = 0.019). The findings suggest that household‑level WASH conditions may be associated with selected placenta‑related complications through both direct and indirect pathways. Water sources, whether unimproved or improved, may be contaminated, and collection, transport, and storage further increase contamination risks while adding a physical burden to water collectors. Unsafe sanitation may also increase exposure to enteric pathogens. Given the observed associations, targeted WASH interventions warrant investigation as a potential strategy to reduce placenta-related complications and improve maternal and neonatal health outcomes in LMICs. Future research should explore the mechanisms linking WASH to pre-eclampsia, SGA, stillbirth and other placenta-related complications, and assess the effect of comprehensive WASH interventions.
