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

Improving lifetime milk yield through the early identification of superior replacement animals is a key objective of sustainable dairy production systems. This study investigated the potential of first-lactation performance indicators to predict lifetime milk yield in dairy cattle managed under subtropical conditions. Historical production records from 349 Holstein, Jersey and crossbred dairy cows maintained at a commercial dairy farm were analysed using linear mixed models, multiple regression and receiver operating characteristic analysis. Estimated lifetime milk yield (ELMY) was calculated from average daily milk yield and lactation length across recorded lactations. Breed, parity, and their interaction significantly influenced several milk production traits (P < 0.05). Holstein cows exhibited the highest (P < 0.05) milk production traits, while milk production increased with advancing parity. Breed-related differences in milk production were evident across parities, with more pronounced variation among breeds at later parities (P
