Geospatial mapping of microbial contaminants and public health risks in Lahore's municipal water.
Article in Scientific reports, 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
Ensuring access to safe drinking water remains a significant public health challenge in developing countries. This study systematically investigates coliform contamination in Lahore's municipal water supply, examining its public health implications, correlation with waterborne disease symptoms, and public perception of water quality. A systematic sampling approach was employed across 381 locations to assess water quality, with water samples analyzed for coliforms and Escherichia coli contamination. Coliform contamination was detected in several areas, including Chungi Amar Sidhu, Charar, Kirianwala, Kharas Mohalla, Shareefpura, Mustafaabad, and Kot Khawaja Saeed. To enhance data robustness, focused case studies with larger sample sizes were conducted in identified hotspots. The average coliform concentration and the percentage of affected households varied significantly across locations, with Shareefpura (3941.4 CFU/ml) and Mustafaabad (1668.2 CFU/ml) exhibiting the highest contamination levels. Mustafaabad also had the highest percentage of affected households (60.3%). Public perception of water quality varied significantly across areas, generally aligning with contamination levels. A Chi-Square Test for Independence showed a significant association between location and public perception (χ
