1 · What the graph read from it

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.

2 · The registry

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

Groundwater is a primary drinking water source in many regions of Bangladesh, necessitating continuous monitoring to ensure safety. This study evaluates groundwater quality in Gazipur City by analyzing 173 water samples collected in 2019 from restaurants across 18 zones. Fourteen physicochemical parameters, including pH, turbidity, total dissolved solids (TDS), electrical conductivity (EC), and major ions, were assessed. Hierarchical cluster analysis grouped the zones into three clusters based on water quality similarities. Three water quality index (WQI) models - integrated WQI (IWQI), assigned weight WQI (AWWQI), and weighted arithmetic WQI (WAWQI) - were applied to assess drinking water suitability. The results showed that 31% (IWQI) and 49% (WAWQI) of samples were unsuitable for drinking. Pearson correlation analysis revealed strong positive correlations among TDS, EC, and color, while negative correlations were observed between pH and color, and fluoride and nitrate. Factor analysis identified industrial effluents, agricultural runoff, and rock-water interactions as major contamination sources. Additionally, microbial analysis confirmed bacterial contamination, with 47% of samples contaminated by
