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
Hybridization between indica and japonica rice combined with utilization of ideal plant type has led to the development of high-yielding japonica rice in northern China. However, the contribution at the genomic level of intersubspecific hybridization to the increased yield of northern Chinese japonica rice is uncertain. In this study, we analyzed the genomic pedigree of descendants of hybridization between indica and japonica rice grown in northeastern China between 1963 and 2008. Simple sequence repeat markers indicated that since 1990 the genetic diversity among northern japonica cultivars was enriched. Genome-wide analysis with subspecies-specific indel and intron length polymorphism markers showed indica-allele frequencies were significantly increased in cultivars bred after 1990, and were significantly positively correlated with spikelet number per panicle and significantly negatively correlated with panicle number per plant. Among eight genes controlling agronomic traits, GN1a and GS3 were partially fixed in the genome of northern japonica cultivars. In contrast, Waxy and qSH1 were eliminated, whereas DEP1 and qSW5 were retained. Indica germplasm is an important contributor to the increased yield of northern japonica rice. Breeding for high yield and grain quality in combination is a complicated process and difficult to achieve when relying on only one or several functional genes, thus the selection expertise of the breeder remains critical.
