PKNOX2 suppresses lung cancer cell proliferation by inhibiting the PI3K/AKT/mTOR axis.
Article in Experimental and therapeutic medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
PBX/knotted 1 homeobox 2 (PKNOX2) has been implicated in tumorigenesis; however, its role in lung cancer (LC) remains unknown. The present study thus aimed to examine the expression, regulation, function and clinical implication of PKNOX2 in LC. A series of experiments were performed, including Cell Counting Kit-8 assay, cell cycle analysis, wound-healing assay, Transwell assay, methylation-specific PCR and western blotting. Bioinformatics analysis revealed that PKNOX2 was a LC-related gene, and a decrease in its expression was found in LC tissues from three public datasets. The results of reverse transcription-quantitative PCR assays also confirmed that PKNOX2 mRNA expression was markedly downregulated in LC tissues (n=60, P<0.01) and in five types of LC cell lines, and this was associated with the promoter methylation of PKNOX2. In addition, PKNOX2 expression was significantly associated with tumor invasion (P<0.0001), lymph node metastasis (P=0.0057) and TNM stage (P=0.0003); however, it was not associated with sex, age, pathological type or distant metastasis.
