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

backgroundFlower color is a well-defined trait in

methodsUntargeted UPLC-MS/MS metabolomics was performed on the reproductive organs of purple- and white-flowered

resultsSix clusters were assigned to 25 metabolites (17 triterpenoid saponins and 8 flavonoids). Flavonoid glycosides were found to possess a conserved inverted V-shaped accumulation pattern in both germplasms. By contrast, saponins derived from triterpenoids showed strong germplasm-dependent accumulation patterns. White-flowered plants showed sustained accumulation, with a peak at the young fruit stage. In purple-flowered plants, accumulation peaked transiently at the withering stage, followed by a decline. PCA validated that metabolic divergence increased with developmental progression.

conclusionsBased on the metabolomic profiles, we hypothesize a putative trade-off model in which floral color divergence may change upstream carbon flux allocation between the triterpenoid saponin and flavonoid pathways. The young fruit stage of white-flowered plants is a candidate harvesting period for bioactive saponins. These conclusions are based only on the pattern of metabolite accumulation and need to be validated by multi-omics.
