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 expression of the genes of carotenoid-cis-trans-isomerases CrtISO, CrtISO-L1, and CrtISO-L2 was studied in comparison with the content of carotenoids in tomato species with different ripe fruit colors: green (Solanum habrochaites), yellow (S. cheesmaniae), and red (S. pimpinellifolium and S. lycopersicum). More ancient origin of CrtISO-L2 in relation to CrtISO and CrtISO-L1 was shown. A similar content of total carotenoids (leaves) and β-carotene (ripe fruits) between the samples was found. Unlike the fruits of S. habrochaites and S. cheesmaniae, the red fruits accumulated lycopene and 20-30 times greater total carotenoids. The highest level of transcripts both in leaves and in ripe fruits was detected for CrtISO. The CrtISO-L1 and CrtISO-L2 genes were transcribed at high levels in leaves and at low levels in fruits, except for the high expression of CrtISO-L2 in S. lycopersicum fruits. No correlation between the content of carotenoids and the level of gene expression in the fruit was observed. In the leaves, a positive correlation between the amount of carotenoids and the levels of CrtISO-L1 and CrtISO-L2 transcripts was found.
