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
Background: Premature rupture of fetal membrane (PROM) is one of the main causes of premature delivery. The amniotic membrane plays a major role in bearing weight, and amniotic fibroblasts play an important role. The purpose of this study was to explore the scientific problems associated with amniotic membrane repair by intervening with fibroblasts to provide evidence for the clinical treatment of PROM. Methods: This research group conducted experiments on fetal membrane tissue via single-cell sequencing, Sirius staining, fluorescence staining and Raman spectroscopy to explore changes in fetal membrane structure and verified key targets and pathways in clinical tissues and primary fibroblasts through WB, PCR, RNA Pulldown, RIP and molecular docking experiments. Results: The fetal membrane structure in the PROM group was obviously damaged, and the amniotic fibroblasts were activated and autophagy was activated, and the activated autophagy promoted the activation of fibroblasts. The expression of Metastasis-Associated Lung Adenocarcinoma Transcript 1 (MALAT1) was significantly increased in amniotic fibroblasts. RNA PULL DOWN and molecular docking results suggested that MALAT1 binds to human E1A promoter repressor 1 (CREG1) and promotes autophagy. Conclusions: By interacting with CREG1, MALAT1 can increase the expression of CREG1, regulate the expression of autophagy-related molecules, mediate the differentiation of amniotic fibroblasts into myofibroblasts, participate in amniotic repair, and promote the repair of PROM fetal membrane tissue.
