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 registryThe 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.

6 · The paper itselfAbstract
Cold stress severely impairs the growth and metabolic composition of tea shoots, thereby limiting tea production. The application of exogenous regulatory substances offers a potential strategy to mitigate cold-induced damage in tea plants. Therefore, identifying endogenous metabolites that could increase cold tolerance and exploring their working mechanisms would be of interest. Here, we identified 292 differentially accumulated metabolites in young shoots of two different tea cultivars through UPLC-MS/MS assays, among which amino acid metabolism was found to be markedly altered. Further analysis revealed that leucine was dramatically induced in all 10 tested accessions. Phenotype, relative electrolyte leakage (REL), and maximum quantum yield of photosystem II (Fv/Fm) analyses revealed that pre-treatment with 20 mM leucine significantly increased the cold tolerance of young shoots in 4 different cultivars. Transcriptome analysis revealed that 48.06% of differentially expressed genes (DEGs), including calcium (Ca
