Morphobiometrical characteristics of indigenous chicken ecotype populations in Rwanda.
Article in Tropical animal health and production, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 rational of conservation and sustainable use of indigenous chicken (IC) resources requires their morphobiometrical characterisation. This study morphobiometrically characterised the IC ecotypes in Rwanda. The morphological features and zoometric measurement data were randomly collected on 1670 mature IC of both sexes from five ecotypes of Rwanda. The nonparametric Kruskal-Wallis and Mann-Whitney U test were used in evaluating the effect of ecotypes on the qualitative morphological variables. Zoometric measurements were analysed with the PROC GLM of SAS. The findings showed that the feather morphology and distribution were mainly normal (98.3 and 84.40%, respectively) while feather colour was dominated with multicoloured (38.10%). The majority of the birds had red earlobe (49.20%), yellow shanks (53.80%) and single comb-type (71.70%). These parameters were different (p < 0.05) between the ecotypes. Bodyweight and linear body measurements were highly different (P < 0.001) between ecotypes. Differences associated with sex (P < 0.001) were observed in body weight and linear body measurements. The interaction between ecotype and sex significantly (P < 0.001) influenced body weight, body length, shank length, comb length, comb height, wattle length, chest circumference, neck length and wingspan. The IC ecotypes in Rwanda were found to be diverse morphobiometrically both in quantitative and qualitative traits. These variations provide a foundation for classification of the chicken into breeds.
