Embryo and cow factors affecting pregnancy per embryo transfer for multiple-service, lactating Holstein recipients.
Article in Translational animal science, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 1 of them a synthesis that pooled it.
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 objective was to determine whether pregnancy success after embryo transfer (ET) during heat stress in multi-service Holstein cows depends upon characteristics of the embryo or recipient. Female embryos produced in vitro were cultured with either 0.0 (control) or 1.8 mM choline chloride and transferred fresh. Fresh embryos of undetermined breed and frozen Holstein embryos were used when experimental embryos were insufficient. Embryos were transferred 8 d after the last GnRH injection of an ovulation synchronization program. Embryo type [frozen vs. fresh, choline vs. control, unknown breed vs. (control + choline)] and characteristics of recipients (average of 190 d in milk at transfer) were evaluated. Pregnancy per ET was lower for cows receiving frozen embryos (7.0%; 3/43) than for cows receiving fresh embryos (26.7%; 32/120) but there were no differences between various types of fresh embryo. Pregnancy per ET was lower for cows diagnosed with metritis in the early postpartum period (7.1%; 2/28) than for cows without metritis (24.4%; 33/135). In conclusion, the use of frozen/thawed embryos produced in vitro and recipients which had metritis in the early postpartum period reduced the success of ET in multiple-service Holstein cows.
