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
key messageFour MaHDZs are possibly involved in banana fruit ripening by activating the transcription of genes related to ethylene biosynthesis and cell wall degradation, such as MaACO5, MaEXP2, MaEXPA10, MaPG4 and MaPL4. The homeodomain-leucine zipper (HD-ZIP) proteins represent plant-specific transcription factors, which contribute to various plant physiological processes. However, little information is available regarding the association of HD-ZIPs with banana fruit ripening. In this study, we identified a total of 96 HD-ZIP genes in banana genome, which were divided into four different groups consisting of 35, 31, 9 and 21 members in the I, II, III and IV subfamilies, respectively. The expression patterns of MaHDZ genes during fruit ripening showed that MaHDZI.19, MaHDZI.26, MaHDZII.4 and MaHDZII.7 were significantly up-regulated in the ripening stage and thus suggested to be potential regulators of banana fruit ripening. Furthermore, MaHDZI.19, MaHDZI.26, MaHDZII.4 and MaHDZII.7 were found to localize exclusively in the nucleus and exhibit transcriptional activation capacities. Importantly, MaHDZI.19, MaHDZI.26, MaHDZII.4 and MaHDZII.7 stimulated the transcription of several ripening-related genes including MaACO5 related to ethylene biosynthesis, MaEXP2, MaEXPA10, MaPG4 and MaPL4 were associated with cell wall degradation, through directly binding to their promoters. Taken together, our findings expand the functions of HD-ZIP transcription factors and identify four MaHDZs likely involved in regulating banana fruit ripening by activating the expression of genes related to ethylene biosynthesis and cell wall modification, which may have potential application in banana molecular breeding.
