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
The aim of this study was to investigate the role of amiloride-sensitive sodium channel protein 1B (SCNN1B) on the proliferation and migration of human lung fibroblasts and the possible mechanism that promote the development of acute respiratory distress syndrome (ARDS). Cultivate human embryonic lung fibroblasts (MRC-5) in vitro and screen out the most effective small interfering RNA to silence the expression of SCNN1B. Then, quantitative real-time PCR (qRT-PCR), CCK-8, Transwell, and Western blot detections were performed separately. The results of qRT-PCR showed that all three SCNN1B siRNAs were able to significantly decrease the mRNA expression level of SCNN1B compared with the si-NC group (P < 0.01), with the most significant decrease in the SCNN1B siRNA-83 group. Additionally, compared with the si-NC group, the proliferation ability of MRC-5 cells in the si-SCNN1B group was significantly enhanced, and the migration rate was significantly decreased (P < 0.01). Western blot results showed that low expression of SCNN1B significantly inhibited the protein expression levels of collagen deposition related proteins Collagen I and Heat shock proteins 47 (P < 0.01). In summary, SCNN1B can inhibit cell proliferation and promote cell migration and extracellular matrix deposition of human lung fibroblasts, and may be involved in the occurrence and development of ARDS.
