Exogenous progesterone supplementation: a strategy to enhance conceptus development in sheep and pigs?
Review in Reproduction & fertility, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Abstract: The inability of animals to get pregnant, pregnancy loss and weak or stillborn offspring are significant economic burdens to livestock producers worldwide. Progesterone, the hormone of pregnancy, has a crucial role in the establishment of pregnancy, and it has been suggested that progesterone supplementation may be a promising strategy to improve pregnancy outcomes and conceptus development. This review article describes the existing literature on progesterone supplementation in sheep and pigs in relation to pregnancy outcomes and conceptus development. Lay Summary: Pregnancy loss and weak offspring are significant problems both in humans and in agriculturally relevant species. Progesterone (the hormone of pregnancy) is important for establishing pregnancy and regulating fetal and placental growth, and it is speculated that progesterone supplementation could be a promising method to improve pregnancy outcomes and both fetal and placental growth. This review article describes the existing literature on progesterone supplementation in sheep and pigs in relation to pregnancy outcomes and fetal and placental development.
