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
Phytoene synthase 1 (PSY1) and capsanthin-capsorubin synthase (CCS) are two major genes responsible for fruit color variation in pepper (Capsicum spp.). However, the role of PSY2 remains unknown. We used a systemic approach to examine the genetic factors responsible for the yellow fruit color of C. annuum 'MicroPep Yellow' (MY) and to determine the role of PSY2 in fruit color. We detected complete deletion of PSY1 and a retrotransposon insertion in CCS. Despite the loss of PSY1 and CCS function, both MY and mutant F2 plants from a cross between MY and the 'MicroPep Red' (MR) accumulated basal levels of carotenoids, indicating that other PSY genes may complement the loss of PSY1. qRT-PCR analysis indicated that PSY2 was constitutively expressed in both MR and MY fruits, and a color complementation assay using Escherichia coli revealed that PSY2 was capable of biosynthesizing a carotenoid. Virus-induced gene silencing of PSY2 in MY resulted in white fruits. These findings indicate that PSY2 can compensate for the absence of PSY1 in pepper fruit, resulting in the yellow color of MY fruits.
