Interleukine-2 serum level in breast cancer patients.
Article in Caspian journal of internal medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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: Breast cancer is a form of cancer that typically affects females. In general, cancer is caused by an imbalance between oncogene and supressor gene factors, including immunity factors against cancer cells. This study aims to compare the levels of IL-2 between breast cancer patients and healthy women, and also compare the levels of IL-2 between HER-2 positive and HER-2 negative, ER/PR positive and ER/PR negative, and among different malignancy grades of breast cancer patients. Methods: This is an observational study using case control method. We include 46 breast cancer patients and 40 healthy women. Blood samples were taken from 46 breast cancer patients (20 HER-2 negative and 26 HER-2 positive patients); 40 of them received hormonal status (29 ER/PR negative and 11 ER/PR positive patients); and from 46 breast cancer patients, 37 of them were divided into malignancy grade. The level of IL-2 was compared between cases and controls and also among the breast cancer patients with HER-2 negative and positive; ER/PR negative and positive; and breast cancer with low, moderate and high grade. Results: IL-2 level was higher in breast cancer patients than in controls (9.400 pg/mL and 3.990 pg/mL respectively, P=0.003). IL-2 level is significantly higher in the breast cancer cases with positive HER-2 compared to negative HER-2 expression (11.154pg/mL and 7.120pg/mL respectively, P=0.001. No association between ER/PR expression nor breast cancer grading with IL-2 level. Conclusion: IL-2 level is higher in breast cancer patients, especially breast cancer patients with HER-2 positive expression.
