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 peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α) is a critical transcriptional coactivator that maintains metabolic homeostasis and energy expenditure by cooperating with various transcription factors. Recent studies have shown that PGC1α deficiency promotes lung cancer metastasis to the bone through activation of TCF4 and TWIST1-mediated epithelial-mesenchymal transition (EMT), which is suppressed by the inhibitor of DNA binding 1 (ID1); however, it is not clear which transcription factor participates in PGC1α-mediated EMT and lung cancer metastasis. Here, we identified forkhead box A1 (FOXA1) as a potential transcription factor that coordinates with PGC1α and ID1 for EMT gene expression using transcriptome analysis. Cooperation between FOXA1 and PGC1α inhibits promoter occupancy of TCF4 and TWIST1 on CDH1 and CDH2 proximal promoter regions due to increased ID1, consequently regulating the expression of EMT-related genes such as CDH1, CDH2, VIM, and PTHLH. Transforming growth factor beta 1 (TGFβ1), a major EMT-promoting factor, was found to decrease ID1 due to the suppression of FOXA1 and PGC1α. In addition, ectopic expression of ID1, FOXA1, and PGC1α reversed TGFβ1-induced EMT gene expression. Our findings suggest that FOXA1- and PGC1α-mediated ID1 expression involves EMT by suppressing TCF4 and TWIST1 in response to TGFβ1. Taken together, this transcriptional framework is a promising molecular target for the development of therapeutic strategies for lung cancer metastasis.
