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
A characteristic trait of the high pigment-1 ( hp-1) mutant phenotype of tomato ( Lycopersicon esculentum Mill.) is increased pigmentation resulting in darker green leaves and a deeper red fruit. In order to determine the basis for changes in pigmentation in this mutant, cellular and plastid development was analysed during leaf and fruit development, as well as the expression of carotenogenic genes and phytoene synthase enzyme activity. The hp-1 mutation dramatically increases the periclinal elongation of leaf palisade mesophyll cells, which results in increased leaf thickness. In addition, in both palisade and spongy mesophyll cells, the total plan area of chloroplasts per cell is increased compared to the wild type. These two perturbations in leaf development are the primary cause of the darker green hp-1 leaf. In the hp-1 tomato fruit, the total chromoplast area per cell in the pericarp cells of the ripe fruit is also increased. In addition, although expression of phytoene synthase and desaturase is not changed in hp-1 compared to the wild type, the activity of phytoene synthase in ripe fruit is 1.9-fold higher, indicating translational or post-translational control of carotenoid gene expression. The increased plastid compartment size in leaf and fruit cells of hp-1 is novel and provides evidence that the normally tightly controlled relationship between cell expansion and the replication and expansion of plastids can be perturbed and thus could be targeted by genetic manipulation.
