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
Root elongation induced by phosphorus deficiency has been reported as one of the adaptive mechanisms in plants. Genetic differences were found in rice for the root elongation under phosphorus deficiency (REP), for which a distinct quantitative trait locus (QTL) was detected on the long arm of chromosome 6. Subsequently, the effect and position of the QTL, designated as qREP-6, were confirmed using chromosome segment substitution lines (CSSLs), in which the background of a japonica cultivar, 'Nipponbare' with non-REP, was partially substituted by chromosomal segments from an indica cultivar, 'Kasalath' with remarkable REP. Out of 54 CSSLs, two lines (CSSL28 and CSSL29) that retain a common 'Kasalath'-derived segment on the long arm of chromosome 6 showed a significantly high REP. The high REP lines also showed high adaptabilities such as enhanced tillering ability and shoot phosphorus content. Accordingly, conditional dependencies between the related traits were assessed using a graphical Gaussian model (GGM). Direct interactions between REP and root length, and between root length and tiller number were detected under P deficiency in CSSLs. Furthermore, qREP-6 for REP and qTNP-6 for tiller number under P deficiency were fine-mapped with an F(2) population of a cross between Nipponbare and CSSL29. A region containing qREP-6 accounted for more than half of the phenotypic variance, the most plausible interval of which contained 37 candidate genes. The result provides a foundation for cloning of the qREP-6 gene which will be applicable to study P deficiency-dependent response and to improve rice's adaptability to P deficiency stress.
