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
Fruit trees, such as apple (Malus x domestica Borkh.), are woody perennial plants with a long juvenile phase. The biological analysis for the regulation of flowering time provides insights into the reduction of juvenile phase and the acceleration of breeding in fruit trees. In Arabidopsis, LIKE HETEROCHROMATIN PROTEIN1 (LHP1) is involved in epigenetic silencing of the target genes such as flowering genes. We isolated and characterized twin apple LHP1 homolog genes, MdLHP1a and MdLHP1b. These genes may have been generated as a result of ancient genome duplication. Although the putative MdLHP1 proteins showed lower similarity to any other known plant LHP1 homologs, a chromo domain, a chromo shadow domain, and the nuclear localization signal motifs were highly conserved among them. RT-PCR analysis showed that MdLHP1a and MdLHP1b were expressed constantly in developing shoot apices of apple trees throughout the growing season. Constitutive expression of MdLHP1a or MdLHP1b could compensate for the pleiotropic phenotype of lhp1/tfl2 mutant, suggesting that apple LHP1 homolog genes are involved in the regulation of flowering time and whole-plant growth. Based on these results, LHP1 homolog genes might have rapidly evolved among plant species, but the protein functions were conserved, at least between Arabidopsis and apple.
