1 · What the graph read from 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.

2 · The registry

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

This study evaluated factors affecting pregnancy outcomes, full-term calving success, and pre-weaning performance following embryo transfer in Holstein-Friesian cattle under commercial farm conditions. A total of 604 in vivo-derived embryos (fresh and frozen-thawed) were transferred into 384 heifers and 220 cows, and pregnancies were diagnosed by ultrasonography. Calves were monitored from birth to weaning. Pregnancy rate per embryo transfer (PR/ET) was higher in heifers than in cows, indicating superior reproductive performance of heifer recipients under field conditions. Recipient corpus luteum (CL) stage II yielded favorable pregnancy outcomes compared to CL stage I, whereas CL stage III comprised a small subgroup (
