A Prospective Study of the Prevalence and Predictive Risk Factors of Repeat Breeder Syndrome in Dairy Cattle in the North of Spain.

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
This study examined the prevalence and risk factors of repeat breeder syndrome (RB) in 2370 dairy cows in northern Spain. Data collected included the prevalence of postpartum pathologies, metabolic markers, and productive and reproductive parameters. The overall RB prevalence was 21.1%. In primiparous cows, the postpartum body condition loss (Odds Ratio (OR): 2.9-8.1, depending on severity), ketosis (OR: 3.5), lameness (OR: 3.4), clinical mastitis (OR: 4.2), dystocia (OR: 5.2), and endometritis (OR: 12.2) significantly increased the RB risk. Summer (OR: 0.4) or autumn (OR: 0.6) calvings reduced this likelihood compared to winter or spring calvings. In multiparous cows, risk factors included body condition loss (OR: 2.0), ketosis (OR: 4.3), lameness (OR: 2.5), clinical mastitis (OR: 4.2), dystocia (OR: 1.9), endometritis (OR: 6.2), metritis (OR: 1.38), and subclinical mastitis (OR: 1.9). A longer interval between calving and first postpartum insemination reduced the RB risk (OR: 0.99). Overall, metabolic and reproductive disorders were significant risk factors for RB across both cow groups, while seasonal calving and delayed insemination mitigated risk in primiparous and multiparous cows, respectively.
