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

Twinning in cattle is an increasingly common reproductive phenomenon that has significant implications for herd productivity and animal welfare. This retrospective study aimed to assess the occurrence rate of twinning (TW) in Italian Holstein multiparous cows and to identify the associated risk factors and consequences with respect to fertility, milk production, and cow survival. Data from 44,535 calvings across 61 Italian dairy farms from January 2019 to December 2020 were analyzed. The overall TW rate was found to be 3.79%, affected by factors such as parity (
