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

Tannins are widespread secondary metabolites that can be induced by herbivory or mechanical damage and contribute to defense against herbivores. Reported tannin inducibility varies across taxa and study designs, making it difficult to separate biological drivers from methodological heterogeneity. Because woodiness covaries with longevity and storage and transport capacity, it may shape inducible chemical defenses, but evidence remains mixed. We synthesized 513 effect sizes from 73 studies, quantified tannin inducibility as the log response ratio (ln
