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

Fixed-time laparoscopic artificial insemination (FT-LAI) using frozen-thawed semen can accelerate genetic improvement in goats, but its efficiency depends on appropriate ovulation synchrony and effective use of cryopreserved spermatozoa. Controlled internal drug release (CIDR) devices and intravaginal fluorogestone acetate sponges are widely used progestogen-based synchronisation tools. However, their comparative performance under tropical field conditions, particularly when reduced sperm doses are used for LAI, remains insufficiently defined. A 2 × 2 factorial field trial was conducted in 175 multiparous Boer × Thai native does to compare synchronisation method (CIDR vs. intravaginal sponge) and insemination dose (150 × 10
