Heavy metal pollution in poultry feeds and broiler chickens in Bangladesh.

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 poultry industry poses a significant threat of heavy metal poisoning for the people of Bangladesh. The research was performed to assess the levels of heavy metals in chicken feed as well as other consumable sections of poultry fowl, and to determine the possible health hazards implicated. The levels of seven metals were evaluated in sixteen commercially available poultry feeds and in three edible portions of chicken obtained from several local markets in Rajshahi city. The metal concentrations were investigated via an atomic absorption spectrophotometer following the wet digestion method. The amount of Cr, Cd, Pb, Cu, Mn, Ni, and Fe in poultry feeds were observed from 0.03 to 12.85 mg/kg, 0.01-1.64 mg/kg, 0.15-4.21 mg/kg, 2.65-45.83 mg/kg, 22.63-188.85 mg/kg, 0.09-2.64 mg/kg, and 0.54-41.01 mg/kg, respectively. In broiler chickens, the concentrations were determined from 0.87 to 3.15 mg/kg, 0.01-0.05 mg/kg, 0.19-1.09 mg/kg, 0.96-3.78 mg/kg, 4.45-23.53 mg/kg, 0.07-0.56 mg/kg, and 2.70-92.32 mg/kg, respectively. With the exception of Cu, Mn, and Fe, most heavy metal concentrations in chickens exceeded the highest allowed concentration set by FAO/WHO. The estimated EDI, THQ and TTHQ numbers for all metals examined were found to be below MTDI, indicating that consumption of chicken meat poses noncarcinogenic risk to individuals. Comparatively, ILCR associated with Cd and Pb are around the safety threshold, but Cr exceeds the permissible range and poses a significant risk.
