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
backgroundPectin methylesterase (PME, EC 3.1.1.11) is a hydrolytic enzyme that utilizes pectin as substrates, and plays a significant role in regulating pectin reconstruction thereby regulating plant growth. Pectin is one of the important components of the plant cell wall, which forms the main structural material of cotton fiber. In this research, cotton genome information was used to identify PMEs.
resultsWe identified 80 (GaPME01-GaPME80) PME genes from diploid G. arboreum (A genome), 78 (GrPME01-GrPME78) PME genes from G. raimondii (D genome), and 135 (GhPME001-GhPME135) PME genes from tetraploid cotton G. hirsutum (AD genome). We further analyzed their gene structure, conserved domain, gene expression, and systematic evolution to lay the foundation for deeper research on the function of PMEs. Phylogenetic data indicated that members from the same species demonstrated relatively high sequence identities and genetic similarities. Analysis of gene structures showed that most of the PMEs genes had 2-3 exons, with a few having a variable number of exons from 4 to 6. There are nearly no differences in the gene structure of PMEs among the three (two diploid and one tetraploid) cotton species. Selective pressure analysis showed that the Ka/Ks value for each of the three cotton species PME families was less than one.
conclusionConserved domain analysis showed that PMEs members had a relatively conserved C-terminal pectinesterase domain (PME) while the N-terminus was less conserved. Moreover, some of the family members contained a pectin methylesterase inhibitor (PMEI) domain. The Ka/Ks ratios suggested that the duplicated PMEs underwent purifying selection after the duplication events. This study provided an important basis for further research on the functions of cotton PMEs. Results from qRT-PCR indicated that the expression level of different PMEs at various fiber developmental stages was different. Moreover, some of the PMEs showed fiber predominant expression in secondary wall thickening indicating tissue-specific expression patterns.
