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
This study aimed to investigate the effect of circular RNA (circRNA) La-related protein 4 (LARP4) on inhibiting the malignant progression of non-small cell lung cancer (NSCLC) cells. CircRNA LARP4 expression in a human normal lung epithelial cell line and NSCLC cell lines was detected by reverse transcription-quantitative polymerase chain reaction. CircRNA LARP4 overexpression and control overexpression plasmids were transfected into NCI-H1650 cells; circRNA LARP4 knockdown and control knockdown plasmids were transfected into A549 cells. CircRNA LARP4 and microRNA (miR)-367 expressions, cell proliferation, apoptosis, migration, and invasion after transfection were investigated. Moreover, the luciferase reporter assay was used to explore the interaction between circRNA LARP4 and miR-367. CircRNA LARP4 was decreased in NSCLC cell lines (including A549, NCI-H1650, NCI-H1299, and HCC827 cells) compared to BEAS-2B cells. In NCI-H1650 cells, circRNA LARP4 overexpression inhibited cell proliferation, migration, and invasion, while promoting apoptosis. In A549 cells, circRNA LARP4 knockdown increased cell proliferation, migration, and invasion, while decreasing apoptosis. Moreover, miR-367 was decreased by the overexpression of circRNA LARP4, but increased by the knockdown of circRNA LARP4; and further luciferase reporter assay revealed that circRNA LARP4 could directly bind to miR-367. In conclusion, circRNA LARP4 is downregulated, suppresses cell proliferation, migration, and invasion, and acts as a sponge of oncogene miR-367 in NSCLC.
