Spatiotemporal dynamics of breast cancer screening across half a million invitations in Geneva, Switzerland.
Article in Communications medicine, 2026. 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
backgroundThe implementation of population-based breast cancer screening programs has been pivotal for early cancer detection, yet sociospatial disparities in participation rates may remain. Understanding and monitoring these variations is essential for improving participation, enabled by modern space-time approaches. This study aimed to (1) assess the existence of spatial clustering of participation in a breast cancer screening program, (2) evaluate temporal shifts in spatial patterns, and (3) assess the relative importance of area-level determinants in predicting participation rates.
methodsWe used the emerging hot spot analysis to mine and visualize space-time participation patterns. We assessed the determinants of screening participation using eXtreme Gradient Boosting combined with SHapley Additive exPlanations values for model interpretation. This approach was applied to a dataset of 482,318 georeferenced invitations sent from 2003 to 2020 by the breast cancer screening program in the canton of Geneva, Switzerland.
resultsHere we show that the overall participation rate of 41.5% falls below the national average of 46%, despite increases across all population segments. Initial analysis shows a clear periurban-urban pattern with lower urban participation. Space-time pattern mining further delineates this pattern into 13 distinct profiles, with rates varying from 27.8% in intensifying cold spots to 49.2% in intensifying hot spots. Modeling reveals higher screening participation in socioeconomically deprived areas and a negative association between accessibility to screening centers and participation rates.
conclusionsThe approach applied in this study enables a more nuanced monitoring of screening participation dynamics. Our findings support targeted interventions in prioritized areas to further reduce cancer screening inequalities.
