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
purposeThe purpose of this study was to analyze the expression patterns of immune cells in renal cancer patients, including myeloid-derived suppressor cells (MDSCs), regulatory T cells (Tregs), CD3 + /CD4 + T cells, CD3 + / CD8 + T cells, and CD3- CD16 + CD56 + cells. In addition, this study will explore the correlation between these immune markers and the progression of renal cell carcinoma and evaluate their potential application in predicting the therapeutic effect of renal cell carcinoma.
methodsIn this study, 80 renal cancer patients who received treatment in our hospital from October 2022 to December 2023 were selected as the research object and 50 healthy people who underwent a physical examination at the same time were selected as the control group. All participants had a 3 ml venous blood sample taken in the morning on an empty stomach. All patients with renal cell carcinoma have been confirmed by histopathological diagnosis. Clinicopathological data including age, gender, BMI, clinical stage, tumor size and pathological type were collected.MDSC, Treg, CD3 + /CD4 + T cells, CD3 + /CD8 + T cells, the ratio of CD3 + /CD4 + T cells/CD3 + /CD8 + T cell and the expression level of CD3-CD16 + CD56 + cells were detected by flow cytometry.
resultsThrough the detection of flow cytometry, we observed that there was no significant difference in gender, age, BMI and other baseline characteristics between renal cancer patients and healthy controls, and the P value was greater than 0.05. However, in the analysis of peripheral blood immune cell subsets, including CD3 + /CD4 + , CD3 + /CD8 + , CD3 + /CD4 + /CD3 + /CD8 + ratio, NK cells, regulatory T cells (T-reg), polymorphonuclear myeloid-derived suppressor cells (PMN-MDSC) and mononuclear myeloid-derived suppressor cells (M-MDSC) were significantly different between renal cell carcinoma group and normal control group (P < 0.05). Specifically, the expression levels of CD3 + /CD4 + and CD3 + /CD8 + cells in renal cancer patients were lower than those in normal subjects, while the expression levels of T-reg, PMN-MDSC and M-MDSC were relatively high. (2) In the flow cytometry analysis, the expression level of immune cell subsets in the peripheral blood of renal cancer patients was detected.The results showed that there was no significant correlation between the expression of CD3 + /CD4 + , CD3 + /CD8 + , CD3 + /CD4 + /CD3 + /CD8 + ratio, NK cells, T-reg cells, PMN-MDSC and M-MDSC and the sex, age, BMI and pathological type of the patients. These differences were not statistically significant (P > 0.05).At the same time, CD3 + /CD8 + T cells, the ratio of CD3 + /CD4 + /CD3 + /CD8 + and the expression level of NK cells were not significantly correlated with tumor size and clinical stage (P > 0.05). However, the expression levels of CD3 + /CD4 + cells, M-MDSC, PMN-MDSC, and T-reg cells were statistically significantly different with tumor size and clinical stage (P < 0.05).There was a significant difference between these indexes and lymph node metastasis (P < 0.05). (3) The results of Logistic regression analysis showed that the low expression of CD3 + /CD4 + lymphocytes and the high expression of T-reg, PMN-MDSC and M-MDSC in peripheral blood may be related to the clinical stage of renal cell carcinoma.
conclusion(1) Compared with healthy individuals, patients with renal cell carcinoma showed a significant decrease in CD3 + /CD4 + T cells, CD3 + /CD8 + T cells and CD3-CD16 + CD56 + cells, while the CD4 + /CD8 + ratio increased. In addition, the number of PMN-MDSC, M-MDSC and T-reg cells was significantly increased compared with the normal population, indicating that the immune system function of patients was impaired. (2) The expression levels of CD3 + /CD4 + , PMN-MDSC, M-MDSC and T-reg were different in tumor size and clinical stage. Specifically, the expression levels of PMN-MDSC, M-MDSC, and T-reg increased correspondingly with the increase in tumor diameter and the progression of the clinical stage.
