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

MAIN

conclusionCPPU treatment increased the supply of carbohydrates in the fruiting branches, and the upregulation of genes related to lignin synthesis improved the tensile strength of the AZ, thereby inhibiting fruitlet abscission in A. catechu. Forchlorfenuron (CPPU) is a synthetic plant growth regulator with cytokinin activity that effectively promotes cell division and expansion, thereby enhancing fruit set rate and improving fruit quality. In this study, CPPU has been verified to effectively suppress fruitlet abscission in A. catechu. The CPPU treatment resulted in a notable increase in the levels of total sugar, starch, sucrose, glucose, and lignin in the abscission zones (AZs) of A. catechu fruitlets. Concurrently, the levels of ACC (1-aminocyclopropane-1-carboxylic acid) and ABA (abscisic acid) significantly decreased, while the levels of ZR (zeatin riboside) and GA
