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
Autophagy, a highly conserved form of cellular recycling, is essential for cellular homeostasis. Its dysregulation has been linked to neurodegenerative diseases and various cancers, including breast cancer. We set out to determine if the RNA-binding protein (RBP) YBX3 regulates autophagy mRNAs, as previous findings suggest YBX3 depletion reduces distinct autophagy transcripts. We found that YBX3 interacts with and stabilizes the mRNA of the autophagy initiation factor ATG13 in HeLa, which in turn increases ATG13 protein expression. We have shown that this requires the 3' untranslated region (UTR) of ATG13 and occurs in other human cell lines, including HEK293, HepG2, and HCT116. Together, our data suggest a novel regulatory role for YBX3 of autophagy initiation through posttranscriptional control of ATG13 mRNA stability.
