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

Storage temperature critically governs physicochemical deterioration and fungal community succession in paddy rice. This study examined quality changes and fungal dynamics in three Yongyou-series hybrid rice varieties stored for 240 days at 15 °C and 25 °C. Fatty acid value (FAV), malondialdehyde (MDA), and electrical conductivity increased progressively, while polyphenol oxidase activity and soluble albumin and globulin contents declined; all changes were more pronounced at 25 °C, indicating accelerated lipid oxidation, membrane damage, and protein structural alteration. ITS amplicon sequencing revealed a gradual shift from field-associated toward storage-adapted fungal taxa. At 25 °C, potentially risk-associated genera-including
