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
Purpose: Lens development requires tight regulation of cell proliferation and differentiation processes, the disruption of which might lead to congenital cataract formation. N6-methyladenosine (m6A) is the most prevalent mRNA internal modification and has been shown to play important roles in regulating the development, physiology, and pathology of various organs and tissues. However, the function of m6A during lens development remains unknown. The purpose of this study was to investigate the function of Mettl3, the core catalytic component of the m6A-writer complex, during lens development. Methods: Lens-specific Mettl3 conditional knockout (Mettl3-CKO) mice were used as a model to investigate the function of Mettl3 during lens development. Hematoxylin and eosin staining was used to examine lens histology. Immunofluorescence (IF) staining was used to examine the expression of genes in the lenses. RNA sequencing (RNA-seq) was used to characterize the transcriptome of the lenses. Modified m6A sequencing was used to characterize the m6A epitranscriptome of the lenses. Results: Mettl3-CKO mice developed cataracts; histologic and IF examination revealed that Mettl3-CKO lenses presented defects in several secondary fiber differentiation processes, including delayed cell cycle exit, mislocalization, and failed cell body elongation. RNA-seq revealed that the expression of genes regulating actin-cytoskeleton dynamics and cell cycle progression was altered in Mettl3-CKO lenses. m6A-seq characterized the lens m6A epitranscriptome and suggested its potential role in regulating fiber cell differentiation processes. Conclusions: Mettl3 regulates lens development by promoting the cell cycle exit and cell morphological changes during secondary lens fiber differentiation.
