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 investigates how melatonin (Mel) supplementation mitigates Lead (Pb) toxicity in rice by evaluating plant growth, physiology, and molecular responses. Pb stress markedly reduced root and shoot lengths by 63% and 33%, respectively, compared to control plants; however, Mel supplementation effectively mitigated this inhibition, enhancing root and shoot lengths by 100% and 47%, respectively, relative to Pb-stressed plants after 10 days. Furthermore, prolonged Mel application under Pb stress sustained growth improvement, increasing root and shoot lengths by 36% and 35%, respectively, compared to Pb-stressed plants. We observed a 19.5% increase in plant height with Mel treatment, along with improvements in yield-related traits such as panicle length and seed weight. Beyond morphological traits, Mel reduced Pb-induced oxidative stress by decreasing [Formula: see text], H
