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

Trace metal contamination of fish poses one of the most critical environmental and health concerns. Although the extent of contamination of aquatic resources in Bangladesh's Kaptai Lake is unknown, the levels of ten trace metals (As, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn) in three commercially important small indigenous fish species (SIS), mola (Amblypharyngodon mola), kaski (Corica soborna), and chapila (Gudusia chapra), were investigated between the dry and rainy seasons. The concentrations of trace metals from SIS were determined using the energy-dispersive X-ray fluorescence system (EDXRF) and implications for evaluating human health risks. The present study shows that all trace metals differed significantly (p < 0.05) among the species and locations except Ni (0.15-0.77 mg/kg) and Se (0.40-1.49 mg/kg) between the dry season and the rainy season. Toxic metals (Cr, Cu, and Zn) in mola, kaski, and chapila had significantly (p < 0.05) higher concentrations than the recommended guideline values. The total hazard quotient (THQ) displayed that the non-carcinogenic effect was lower as observed in both children and adults, with the rainy season reflecting more non-carcinogenic risks than the dry season. The hazard index (HI) value for SIS in both seasons (8.66-71.80 × 10
