Semiparametric approaches for mitigating spatial confounding in large environmental epidemiology cohort studies.
Article in Environmetrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Epidemiological analyses of environmental risk factors often include spatially-varying exposures and outcomes. Unmeasured, spatially-varying factors can lead to confounding bias in estimates of associations with adverse health outcomes. Several approaches for mitigating this bias have been developed using semiparametric splines. These methods use thin plate regression splines to account for the spatial variation present in the analysis but differ in how to select the amount of spatial smoothing and in whether the exposure, the outcome, or both are smoothed. We directly compare current approaches based on information criteria and cross-validation metrics, and additionally introduce a hybrid method to selection that combines features from multiple existing approaches. We compare these methods in a simulation study to make a recommendation for the best approach for different settings and demonstrate their use in a study of environmental exposures on birth weight in a Colorado cohort.
