Effect of gonadotropin administration on reproductive performance in relation to the age at first conception, time of application, and body condition of weaned sow.
Article in Archives animal breeding, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 administration of hormone preparations to synchronize the onset of oestrus in gilts and sows is a good way of achieving breeding objectives economically on large-scale farms. Therefore, the objective of this study was to analyse the effects of the timing of administration of gonadotropins (400 IU (international unit) eCG - equine chorionic gonadotropin - and 200 IU hCG - human chorionic gonadotropin; Intervet International B.V.), the age of gilts at first conception, and their backfat thickness (BFT) at weaning on the length of weaning to oestrus interval (WEI) and litter size in the following four parities. A total of 578 crossbred sows (
