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

Background: Dystocia is an uncommon but potentially life-threatening complication of equine parturition. Due to early separation of the chorioallantois during the expulsive stage, fetal oxygen supply rapidly becomes compromised, making dystocia a time-critical emergency for both mare and foal. Objectives: To describe obstetrical interventions performed at equine referral hospitals, evaluate mare and foal survival, and identify factors associated with survival outcomes in a Swedish population where geographic distances may influence access to specialized veterinary care. Methods: Medical records from three equine referral hospitals in central Sweden were reviewed for dystocia cases presented between January 2006 and December 2022. Data collected included dystocia causes, obstetrical interventions, dystocia duration, prior veterinary intervention, and survival outcomes for mares and foals. Results: A total of 138 dystocia cases were included. Fetal causes of dystocia predominated (114/138), with malposition being most common (106/138). Controlled vaginal delivery was the most frequently performed intervention (33.3%, 46/138). Of 140 foals delivered, 17.1% were born alive and 12.1% survived hospital discharge. Foal survival was not different among delivery methods ( Conclusion: Duration of dystocia prior to hospital admission was a key factor associated with neonatal survival, highlighting the importance of early recognition of dystocia, close monitoring of mares approaching foaling, and prompt referral to specialized equine hospitals.
