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

Aquatic medicinal plants are widely consumed in Ghana, yet their safety is threatened by contamination from polluted water bodies. This study examined concentrations of arsenic, cadmium, lead, copper, and zinc in twelve hydrophyte species from rivers in Mampong Municipality and assessed associated health risks. Samples were digested using nitric acid and analyzed by atomic absorption spectrometry (AAS). Method validation yielded recovery rates between 90-110% and detection limits of 0.001-0.01 mg/kg, confirming high analytical accuracy and precision. Mean concentrations showed substantial accumulation, especially in roots and leaves, with As, Cd, and Pb often exceeding WHO limits. Statistical analysis revealed significant species- and part-level variation only for Cu and Zn, whereas As, Cd, and Pb accumulated uniformly across taxa and tissues. Exposure assessment demonstrated that estimated daily intakes (EDIs) of As, Cd, and Pb from several species exceeded recommended thresholds. Hazard quotients (HQ) and hazard indices (HI) were frequently above the safety limit of 1.0, indicating potential non-carcinogenic risks, with children consistently more vulnerable than adults. Carcinogenic risk (CR) values for As were above the acceptable range (10⁻⁶-10⁻
