Litter size, litter weight, and lamb survivability of Doyogena sheep managed under community-based breeding program in Ethiopia.
Article in Heliyon, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
Increasing litter size and weight during the marketing time by decreasing mortality among lambs per ewe is the objective of the community-based breeding program (CBBP). This study aims to find out litter size, litter weight per ewe, and preweaning lamb mortality of Doyogena sheep managed under CBBP. The study analyzed the data records of 4530 animals for 8 years from 2013 to 2020. A logistic regression procedure was used to analyze pre-weaning lamb survival rates. Results showed that the overall least-squares means of litter size at birth (LSB), litter size at weaning (LSW), total litter weight at birth (TLWB), and total litter weight at weaning (TLWW) were 1.57 ± 0.02 lambs, 1.50 ± 0.02 lambs, 5.24 ± 0.09 kg, and 24.14 ± 0.69 kg respectively. The incidence of pre-weaning lamb mortality was 4.72%. Year and breeder cooperative vary were observed for pre-weaning lamb losses. Females had lower odds of survival as compared to males. Odds of survival were low for triplets, quadruplets, and low birth weight (≤2 kg) born lambs. The ongoing selection program which aims to improve reproductive and growth performance had a positive influence on the survival rate of lambs. Improvement of the environment in the flock, special care for multiple-born and care for small lambs would lead to further lamb survival improvements.
