Chinese Medicine Enhancing Response Rates to Immunosuppressant PD-L1 Inhibitor and Improving the Quality of Life of Hepatocellular Carcinoma-Bearing Mice.
Article in Iranian journal of pharmaceutical research : IJPR. 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
Background: Malignant tumors are a significant disease endangering human health. Chinese Medicine (CM) plays an important role in comprehensive and holistic tumor treatment. Objectives: We aimed to investigate whether CM combined with the immunosuppressant PD-1/PD-L1 inhibitor has a good synergistic effect and can significantly improve response rates for the immunosuppressant. Methods: We combined CM with immunosuppressant in treating six-week-old hepatocellular carcinoma-bearing mice and compared the outcomes of groups undergoing different interventions: blank group, control group, CM group, PD-L1 inhibitor group, and CM + PD-L1 inhibitor group, with ten mice in each group. The quality of life was evaluated along with the tumor inhibition effects and growth rates. Results: CM significantly reduced tumor load and improved the quality of life of cancer-bearing mice. The survival rate was 81.8% in the control group, 100% in the CM group, 90.9% in the PD-L1 inhibitor group, and 100% in the combined group in the first week. The survival rate was 45.5% in the control group, 54.5% in the CM group, 81.8% in the PD-L1 inhibitor group, and 81.8% in the combined group in the second week. 38% mice in the CM+PD-L1 inhibitor group with smaller tumor size than the average of the control group, which was much higher than other treatment groups. CM also reduced the expression of JAK2 mRNA and STAT3 mRNA, although not significantly (P > 0.05), and reduced PD-L1 mRNA in tumor tissue compared to the control group (P < 0.05). Conclusions: CM had a synergistic effect on PD-L1 inhibitors and increased response rates to PD-L1 inhibitor treatment.
