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
introductionNon-small cell lung cancer (NSCLC) is a type of malignant tumor with high morbidity as well as mortality. The process of lung cancer may be driven by cancer stem cells. It was known that MFAP5 enhanced the occurrence of diverse types of cancer. Also, MFAP5 has the potential to induce the degradation of FBW7 which is a tumor suppressor. Lower levels of FBW7 enhance the stability of Sox9, which is the cancer stem cell-related protein. However, whether the MFAP5 can modulate the stem cell features of NSCLC cells by modulating the FBW7/Sox9 axis is unclear. Therefore, this study aimed to explore the role of MFAP5/FBW7/Sox9 axis on the stem cell features of NSCLC cells and develop a new treatment of this carcinoma. MATERIAL AND
methodsIn this study, we explored the effects of MFAP5 on the stem cell features of NSCLC cells for the first time. We established MFAP5 overexpression and knockdown NSCLC cells. Clone formation assays and cell sphere culture assays were conducted for the exploration of the growth and stem cell features of these cells. Western blotting was applied for the detection of Sox9 and FBW7 expression in these cells. CHX was applied for the treatment of these cells for the detection of degradation of Sox9. Finally, we overexpressed the Sox9 in MFAP5 knockdown NSCLC cells.
resultsMFAP5 promoted the growth and stem cell features of these cells. Knockdown of MFAP5 induced higher levels of FBW7 while restricting the expression of Sox9. Knockdown of MFAP5 aggravated the degradation of Sox9. Overexpression of Sox9 abrogated the efficacy of MFAP5 inhibition on the growth as well as stem cell features of these cells. The results of this study clarified the role of MFAP5/FBW7/Sox9 axis on the development of non-small cell lung cancer cells, providing the potential therapeutic target for the clinical treatment of NSCLC.
conclusionMFAP5 maintained the stem cell features of non-small cell lung cancer cells by modulating FBW7/Sox9 axis.
