[Aumolertinib inhibits growth of human choroidal melanoma MUM-2B cells
Article in Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the inhibitory effect of aumolertinib on proliferation of human choroidal melanoma MUM-2B cells and explore the possible molecular mechanism.
methodsCCK-8 assay and colony formation assay were used to evaluate the inhibitory effect of different concentrations of aumolertinib on viability and proliferation of MUM-2B cells. Flow cytometry was performed to analyze the apoptosis, necrosis, cellular ROS production and cell cycle changes in aumolertinib- treated MUM-2B cells. The antitumor effect of aumolertinib against human choroidal melanoma was observed in nude mouse models bearing MUM-2B tumor cell xenografts.
resultsThe results of CCK-8 and colony formation assay showed that aumolertinib strongly inhibited the proliferation MUM-2B cells in a dose-dependent manner. Flow cytometry showed that aumolertinib dose-dependently increased the total apoptosis rate of MUM-2B cells to as high as 76.65% at the concentration of 8 μmol/L and induced obvious cell cycle arrest at G1 phase. Aumolertinib treatment also caused a dose-dependent increase of ROS production and reduction of mitochondrial membrane potential in MUM-2B cells. In the tumor-bearing nude mice, treatment with aumolertinib significantly inhibited tumor growth without causing obvious body weight loss.
conclusionAumolertinib can effectively inhibit the growth of human choroidal melanoma MUM-2B cells both
