Prediction of Lead Intake and Tissue Lead Concentrations in Broiler Chickens Using Feather Lead Concentrations.
Article in Biological trace element research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 present experiment was conducted to derive equations for predicting daily lead (Pb) intake and tissue Pb concentrations in broiler chickens using feather Pb concentrations. A total of 800 3-day-old broiler chickens were allotted to one of five dietary treatments with 16 replicates, each replicate consisting of 10 birds, in a completely randomized design. Dietary Pb concentrations were set to 0, 50, 100, 200, or 400 mg/kg by adding a lead acetate. The experimental diets were provided ad libitum for 32 days. Results indicated that growth performance and serum measurements were not affected by increasing concentrations of Pb in diets, which represented that the toxic level of dietary Pb may exceed over 400 mg/kg in broiler diets. Increasing concentrations of Pb in diets increased Pb concentrations in the liver (linear and quadratic, P < 0.05), breast (linear, P < 0.01), and feather (linear, P < 0.01). Feather Pb concentrations were greater than Pb concentrations in the liver and breast, indicating that the feather is highly responsive tissue of broiler chickens to various dietary Pb concentrations. Consequently, the equations for predicting daily Pb intake and Pb concentrations in the liver and breast were derived from Pb concentrations in the feather. Resulting equations indicated that feather Pb concentrations in broiler chickens can be used to predict both daily Pb intake and Pb concentrations in the liver and breast.
