Use of serum total protein as a proxy for passive transfer status in lambs.
Article in The Veterinary record, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundSerum total protein (TP) is commonly used to investigate failure of passive transfer of immunity (FPTI) in cattle. This short communication explores the use of serum TP as a proxy of passive transfer (PT) status in lambs.
methodsBlood samples were obtained from 434 lambs within 8‒24 hours of birth to measure serum immunoglobulin G (IgG) and TP. The relationship between serum IgG and TP was described using a linear regression model. Receiver operating characteristic analysis was used to select a serum TP cut-off for sub-optimal PT.
resultsThere was a moderate positive relationship between serum IgG and TP (r LIMITATIONS: This work involved lowland lambs sampled from a single well-managed farm. Further work is needed to establish FPTI cut-offs in a variety of sheep populations.
conclusionsSerum TP measurement is an appropriate field diagnostic to estimate the PT status of lambs in lowland flocks.
