Pollution status of major rivers in an agricultural belt in Eastern Nigeria.
Article in Environmental monitoring and assessment, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 physico-chemical and bacteriological analyses of four rivers namely: Ajali, Obinna, Karawa and Adada in Ezeagu and Uzo-uwani Local Government Areas (LGAs) of Enugu State, South-eastern Nigeria, were carried out to evaluate their suitability for consumption. Water samples from Ajali River were taken from a point where the river receives brewery effluents and other two points that were impacted by non-point pollution sources. A total of 54 water samples were collected during the dry season, early rainy season and rainy season proper for 2 years. For each trip, nine samples were collected from three sampling points in Ajali and two each in Adada, Obinna and Karawa. The water quality index (WQI) was calculated using the arithmetic index method. Significant seasonal and spatial variations (p < 0.05) were evident for sulphate, phosphate, sodium, magnesium, pH, total alkalinity, nitrate and total dissolved solids. Mean values of WQI were 71.75 ± 16.07 57.26 ± 5.39, 60.47 ± 13.12, and 66.75 ± 15.30 for Adada, Obinna, Karawa and Ajali, respectively.
