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
objectivePolypeptide N-acetylgalactosaminyltransferase 7 (GALNT7) is a glycopeptide transferase which is closely involved in the development and progression of cancer. This study aimed to investigate the effects of GALNT7 inhibition on non-small cell lung cancer (NSCLC) cell proliferation, apoptosis and invasiveness and to determine whether these effects are mediated by the protein kinase B (AKT) pathway.
methodsNegative control small interfering RNA (siRNA) (si-NC) and siRNA targeting GALNT7 (si-GALNT7) were transfected into A549 and NCI-H1650 cells. Afterwards, the AKT activator '740 Y-P' was added to treat the cells with or without siRNA transfection.
resultsCell proliferation was reduced after si-GALNT7 transfection compared with si-NC transfection at 24 hours, 48 hours and 72 hours in A549 cells, and at 48 hours and 72 hours in NCI-H1650 cells. Furthermore, the cell apoptosis rate was increased, but the cell invasive number was decreased after si-GALNT7 transfection compared with si-NC transfection in A549 cells and NCI-H1650 cells. Phosphorylated (p)-AKT/AKT expression was lower after si-GALNT7 transfection compared with si-NC transfection in A549 cells and NCI-H1650 cells. Worth noting, the effects of si-GALNT7 transfection on the above-mentioned cell proliferation, apoptosis and invasiveness were repressed by the addition of 740 Y-P in A549 cells and NCI-H1650 cells.
conclusionGALNT7 inhibition suppresses NSCLC cell proliferation and invasiveness while increasing apoptosis through inactivation of the AKT pathway.
