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

A lactation length (LL) of 305 days in milk (DIM) does not fully represent the reality of milk yield and a great part of lactations extend beyond that period. This study aimed to compare the parameters of extended lactation curves with the traditional 305 DIM, considering parity orders (PO) in Holstein (HOL) and Jersey (JER) cows. Data were collected from 33,524 cows (31,194 HOL and 2,330 JER) across 544 dairy farms in Paraná, Brazil. Cows were classified by PO (primiparous, secundiparous, and multiparous) and LL, defined based on calving intervals of 11 to 13 months (LL305
