Reproductive Efficiency in Sheep: Estimates and Relationships with Fertility, Fecundity and Lamb Survival.
Review in Animals : an open access journal from MDPI, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Addressing increased demand for sheep meat globally is dependent on reproductive efficiency (lambs weaned per 100 breeding ewes). Efficiency is determined by ewe fertility (pregnancy rate) and fecundity (litter size), as well as lamb survival. This paper provides estimates of these components from the world literature and examines their relationships with breed class (wool, dual-purpose, meat, milk, prolific) and within breed class, country and global region. Reproductive efficiency was estimated at 97.7 ± 2.68, while values for fertility, fecundity and lamb survival were 83.9 ± 0.95, 144.6 ± 3.48 and 80.8 ± 0.93%, respectively. Efficiency increased for each component, with the response being greatest for fecundity (R
