Hydrochemistry and Water Quality Index of groundwater resources in Enugu north district, Enugu, Nigeria.
Article in Environmental monitoring and assessment, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
The physicochemical parameters of groundwater in 12 cluster boreholes in Enugu North district/region, southeast Nigeria, were studied. Twelve physicochemical parameters were determined in triplicates at monthly intervals for 3 months in dry season and then repeated in rainy season in 120 boreholes grouped into 12 clusters for 2 years. The range of values obtained during dry season include phosphate (0.12-0.87 mg/L), nitrate (1.24-8.72 mg/L), sulfate (20.10-24.34 mg/L), pH (4.9-7.5), E.C. (10.0-410.0 μS/cm), total acidity (0.06-1.24 mg/L), total alkalinity (28.0-22.10 mg/L), total hardness (100.0-140.1 mg/L), TSS (70.0-270.0 mg/L), TDS (0.00-210.0 mg/L), TS (70.0-390.0 mg/L), and turbidity (3.4-50.0 mg/L) while rainy season values were phosphate (0.30-10.60 mg/L), nitrate (1.20-120.0 mg/L), sulfate (0.0-100.0 mg/L), pH (4.9-7.5), E.C. (10.0-360.0 μS/cm), total acidity (0.10-10.5 mg/L), total alkalinity (10.0-52.1 mg/L), total hardness (100-130 mg/L), TSS (100.0-280.0 mg/L), TDS (0.0-260.0 mg/L), TS (110.0-560.0 mg/L), and turbidity (3.80-56.0 mg/L). When compared with standard guideline values recommended by regulatory bodies, rainy season nitrate values in some samples and phosphate mean values were higher than recommended values. Seasonal variations of the parameters in the samples were observed. Statistical analysis showed statistically significant variations between the 12 borehole water physicochemical parameters in dry and rainy seasons. Water quality index (WQI) analysis categorized all the water samples within the range of good to excellent.
