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

This study compared fertility and parturition parameters in Limousin (L) and Charolais (C) heifers to identify the breed most suitable for beef production. A total of 234 L and 76 C Hungarian-origin heifers, aged 9-11 months, were managed under standardized housing and feeding conditions at Dogan Farm. Parturitions were categorized based on the time of day (day: 07:00-19:00; night) and season (cold, cool, hot). Statistical analyses were conducted using ANOVA and Chi-square tests Results showed that C heifers required significantly more inseminations to conceive (C: 3.39 ± 0.22, L: 2.32 ± 0.10, P < 0.0001), indicating lower reproductive efficiency. Additionally, C calves were significantly heavier at birth than L calves (C: 46.1 ± 0.8 kg, L: 40.2 ± 0.3 kg, P < 0.0001), with male calves being generally heavier than females (M: 43.7 ± 0.5 kg, F: 39.5 ± 0.3 kg, P < 0.0001). The incidence of dystocia was higher in C heifers (63.16%) compared to L heifers (41.88%), while L heifers experienced greater parturition ease (58.12% vs. 36.84%; X
