Occurrence and health risk assessment of trace and heavy metals in four wastewater treatment plants and their receiving surface waters in Gauteng Province, South Africa.

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
Wastewater treatment plants (WWTPs) receive high volumes of domestic and industrial effluents, which are endowed with varying levels of metallic elements. If not properly treated WWTPs effluents discharged into river systems contribute to their contamination. This work reports on the ubiquitous detection of metals (As, Cd, Co, Cr, Cu, Fe, Mn, Pb, Ni, Zn) in WWTPs influents, effluents, sludge and water from the receiving rivers located in the Gauteng Province in South Africa. In wastewater, calculated mean metal concentrations ranged between 0.132 and 4.914 mg L
