Spatiotemporal variability of surface water quality in tropical agriculture-dominated catchments: insights from water quality indices.
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 4 papers.
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
Surface water quality in tropical, agriculture-dominated catchments faces intense pressure from human activities, yet comprehensive, index-based assessments for these regions remain limited. This study aimed to use an index-based assessment to examine the spatial and temporal changes in water quality within the Maziba catchment in southwestern Uganda, characterised by increasing land-use pressures. Monthly surface water samples were collected from 16 stations between July 2023 and June 2024 to analyse physicochemical parameters. The study employed the Weighted Arithmetic Water Quality Index (WAWQI) for assessing drinking water suitability, the Comprehensive Pollution Index (CPI) for evaluating aquatic ecosystem health, and a new combined risk framework to deliver an integrated, stakeholder-oriented assessment. WAWQI results ranged from "good" to "unfit for consumption", with 69% of stations classified as "poor" to "unfit". CPI indicated "slight pollution" on average. Notably, the integrated risk assessment did not classify any stations as "Low Risk", while most were classified as "High Risk" (50.0%) or "Severe Risk" (18.8%). Human activities and seasonal changes have a significant impact on water quality deterioration in the Maziba catchment. The simultaneous decline in water suitability for drinking and ecosystem health underscores the need for integrated management strategies that target both diffuse and point-source pollution to protect public health and aquatic ecosystems.
