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
The pigmentation patterns of potato tubers are complex and diverse, often exhibiting significant tissue specificity. This study was conducted to elucidate the molecular mechanisms underlying the differential pigmentation in different parts of potato tubers using two cultivars, 'Huashu 12' and 15EM36-26, which exhibit opposite pigmentation patterns between the bud eyes and the tuber periderm. Metabolomic analysis revealed that cyanidin, pelargonidin, and malvidin are the key anthocyanin components responsible for the observed pigmentation differences. A total of 118 common differentially expressed genes in the differentially pigmented tissues of both cultivars were identified in transcriptomic analysis, including key structural genes of the anthocyanin biosynthesis pathway (such as
