METTL14-Mediated N6-Methyladenosine Exacerbates Acute Lung Injury via USP30/NCOA4-Dependent Ferroptosis.

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
Ischemia/reperfusion (I/R)-induced acute lung injury (ALI) is a severe clinical syndrome characterized by alveolar epithelial damage, oxidative stress, and acute respiratory failure, but the epitranscriptomic mechanisms linking N6-methyladenosine (m6A) modification to ferroptosis remain unclear. Clinical profiling of end-stage acute respiratory distress syndrome (ARDS) patients showed hyperinflammation, reflected by elevated C-reactive protein and procalcitonin, coagulopathy with abnormal D-dimer levels, and severely impaired gas exchange. Reanalysis of a public murine single-cell RNA sequencing dataset revealed enrichment of RNA methylation-, ubiquitination-, and ferroptosis-related programs in injured lung epithelial cells. Integrated methylated RNA immunoprecipitation sequencing and RNA sequencing of I/R-injured mouse lungs further identified methyltransferase-like 14 (METTL14) and YTH N6-methyladenosine RNA-binding protein 1 (YTHDF1) as candidate m6A regulators. Human ARDS tissues and mouse I/R lungs confirmed increased METTL14, ubiquitin-specific peptidase 30 (USP30), and nuclear receptor coactivator 4 (NCOA4) expression. Mechanistically, METTL14-mediated m6A modification enhanced USP30 expression through YTHDF1 recognition, whereas USP30 stabilized NCOA4 by reducing K48-linked polyubiquitination. Stabilized NCOA4 promoted ferritinophagy, Fe
