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

Hepatitis E virus (HEV) is an important zoonotic pathogen and a major cause of acute viral hepatitis worldwide. Domestic pigs are the primary reservoir of zoonotic HEV genotypes 3 and 4, making surveillance in pig populations important for understanding HEV epidemiology. However, updated data on HEV seroprevalence in Taiwanese pig populations remain limited. This cross-sectional study investigated the seroprevalence of HEV among fattening pigs in Taiwan. A total of 356 serum samples were collected from 32 commercial farms across five major pig-producing counties during 2024-2025 and tested for anti-HEV IgG by ELISA. Serum samples with sufficient residual volume (
