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

importanceSnow leopards ( CASE PRESENTATION: A 9-year-old female snow leopard at Seoul Zoo, housed with a male since 2003 without previous conception, underwent two estrus induction attempts. In the first trial, 600 IU pregnant mare serum gonadotropin (PMSG) followed by 300 IU human chorionic gonadotropin resulted in mating but only a pseudopregnancy. A portable wooden restraining box with a squeezing panel enabled accurate hormone injection using hand syringes. After a 97-day separation period, a second trial involved a single injection of 600 IU PMSG. After reintroduction to the male, multiple matings occurred for eight days, and a single cub was delivered 94 days after the first mating. The cub nursed normally for two days but died due to maternal infanticide. CONCLUSIONS AND RELEVANCE: This case shows that reliable estrus induction and parturition in snow leopards can be achieved with a single PMSG injection when supported by a customized restraining box that ensures accurate hormone delivery. This method offers a practical approach to assisted reproduction in difficult-to-handle snow leopards and other felids.
