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.
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
The high demand for energy during floral thermogenesis drives the synergistic operation of multiple energy substrates for the rapid temperature rise and successful reproduction of flowers. However, how thermogenic plants precisely regulate substrate supply and metabolic pathways within a short time to support large-scale energy and heat release remains a mystery. This study revealed the elaborate synergistic supply mechanism of multi-source substrates in Magnolia denudata during thermogenesis. Transcriptome analysis showed that genes related to the tricarboxylic acid (TCA) cycle and oxidative phosphorylation (OXPHOS) were significantly upregulated during the thermogenic stage (S2). Mitochondrial feeding assays using isotopically labelled substrates revealed that during the thermogenic stage, both the amount of pyruvate imported via the mitochondrial pyruvate carrier (MPC) and NAD-malic enzyme (NAD-ME) increased, and their synergistic effect accelerated the metabolic flow of the TCA cycle. Targeted lipidomics analysis indicated that the content of 63.6% fatty acids in the fatty acid degradation pathway decreased, while the key enzyme genes involved in triacylglycerol lipase (TGL) and fatty acid β-oxidation pathways were highly expressed during the thermogenic stage. In addition, enhanced expression of genes related to alanine aminotransferase (AlaAT) and glutamate dehydrogenase (GDH) suggested that amino acid metabolism might provide additional substrates for thermogenesis. This study clarifies the synergistic energy supply of carbohydrate, fatty acid and amino acid metabolism during thermogenesis in M. denudata, providing new evidence for understanding the metabolic regulatory flexibility of floral thermogenesis in plants.
