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 needle-free jet injection (NFI) with conventional needle vaccination in finishing pigs, evaluating growth performance, carcass quality, serum cortisol, macroscopic injection-site safety, and Classical Swine Fever (CSF)-specific neutralizing antibody responses. Twenty-four 3-week-old crossbred pigs were randomly assigned to receive both CSF and Foot-and-Mouth Disease (FMD) vaccines into the mid-neck muscle via either conventional needle (control) or an electromagnetic NFI device. Growth metrics, including body weight, average daily feed intake (ADFI), and feed conversion ratio (FCR), were monitored weekly. Serum cortisol was measured 30 min post-vaccination to assess acute stress. CSF antibody titers were determined at 6, 8, 12, and 14 weeks of age (0, 14, 42, and 56 days post-vaccination; dpv). Carcass traits and internal tissue integrity were assessed post-slaughter. Results showed no statistically significant differences (
