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
Background: Abscisic acid (ABA) is a well-studied phytohormone demonstrated to be involved in sub-sets of stress responses in plants, such as iron (Fe) deficiency and phosphorus (P) deficiency in Arabidopsis. However, whether ABA is involved in P deficiency in rice has not been frequently studied. The present study was undertaken to investigate the mechanism underlying ABA-aggravated P deficiency in rice (Oryza sativa). Results: P deficiency decreased ABA accumulation rapidly (within 1 h) in the roots. Exogenous ABA negatively regulated root and shoot soluble P contents by decreasing pectin content, inhibiting P deficiency-induced increases in pectin methylesterase activity and expression of the phosphate transporter gene-OsPT6, thereby decreasing the re-utilization of P from the cell wall and its translocation to the shoot. Moreover, neither the nitric oxide (NO) donor sodium nitroprusside nor ethylene precursor 1-aminocyclopropane-1-carboxylic acid had any effect on ABA accumulation, and application of ABA or the ABA inhibitor fluridone also had no effect on NO production and ethylene emission. Conclusions: Under P deficiency, NO levels increase as quickly as ABA levels decrease, to inhibit both the ABA-induced reduction of pectin contents for the re-utilization of cell wall P and the ABA-induced down-regulation of OsPT6 for the translocation of P from roots to shoots. Overall, our results provide novel information indicating that the reduction of ABA under P deficiency is a very important pathway in the re-utilization of cell wall P in rice under P-deficient conditions, which should be a very effective mechanism for plant survival under P deficiency stress for common agronomic practice.
