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 aimed to investigate the effects of dietary tea polyphenols (TPs) supplementation on growth performance and meat quality. A total of 120 pigs ([Yorkshire × Landrace] × Duroc) aged 150 days with similar body weights (74.29 ± 0.55 kg), comprising equal numbers of females and castrated males, were randomly assigned to two treatments, each with three pens of 20 pigs: The Control group received a basal diet, and the TP group received the basal diet supplemented with 2000 mg/kg tea extract containing 15% TP. A 7-day adaptation preceded the 60-day feeding period. At the end of the experiment, the final bodyweight of the pigs was measured and six pigs per treatment were selected for sampling. The results showed that: (1) growth performance did not differ significantly, although feed-to-gain ratio and average daily feed intake were numerically lower in the TP group; (2) carcass weight, backfat thickness, and muscle alanine increased, whereas
