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
The aim of this study was to investigate the impact of the antibiotic lidamycin (LDM) and the targeted therapy with the antibody Myosin heavy chain 9 (MYH9) on cancer cells, aiming to provide insights for cancer treatment. In this study, antibiotics and targeted antibodies were used in cancer cells, and then their effects on cell growth, proliferation, apoptosis regulation, and related proteins were measured, and comparative analysis was conducted on the effects of different drug concentrations on the growth of cancer cells. In H460, the apoptotic effect of 2 nM LDM on cells reached 70%. LDM had a downward trend on the levels of B-cell lymphoma-2 (Bcl-2) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) in cells. The inhibitory effects of LDM at different concentrations on human large cell lung cancer H460 transplanted tumor in nude mice reached 53.20% and 69.80%, and the inhibitory effects on the growth of lung adenocarcinoma transplanted tumor in nude mice reached 40.20% and 58.30%. The expression of MYH9 (myosin, heavy polypeptide 9, non-muscle) in human lung cancer tissues and adjacent tissues reached more than 80%. At the concentration of 300 μM, antibody MYH9 inhibited cell growth by 30%, and the migration rate was also reduced by 25%. The inhibitory effect of siRNA after knocking out the MYH9 gene on cancer cells reached 70%. Antibiotic LDM and targeted antibody MYH9 can inhibit the growth, proliferation, and migration of cancer cells, promote cancer cell apoptosis, and have certain clinical significance for the treatment of cancer patients.
