The expression of androgen receptor in triple-negative breast cancer and the effect of a traditional Chinese medicine formula on disease-free survival.
Article in Gland surgery, 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
Background: Androgen receptor (AR) is becoming an important factor in the pathogenesis of breast cancer. Traditional Chinese medicine (TCM) is widely used in treating breast cancer patients. Triple-negative breast cancer (TNBC) is a subtype of breast cancer, which has worse prognosis than other subtypes. Herein, through this retrospective study, we summarize the therapeutic implications of AR and TCM in TNBC. Methods: The clinical and pathological data of TNBC patients who had undergone surgery at The First Affiliated Hospital of Zhejiang Chinese Medical University from 2017 to 2019 were collected and examined. The Results: We identified 823 early breast cancer patients from January 2017 to December 2019, of whom 92 (11.2%) were pathologically confirmed to have TNBC. We excluded 5 patients according to the inclusion and exclusion criteria. In relation to the remaining 87 patients, 33 (37.9%) were AR positive. In the TNBC patients, positive AR expression was correlated with an older age (P=0.006), a higher weight (P=0.006), and lower Ki-67 expression (P=0.031). After a median follow-up time of 37 months (range, 24-60 months), 13 cases of relapse and metastasis (14.9%) were observed. We found that relapse and metastasis were correlated with being unmarried [P=0.004; hazard ratio (HR) =0.105; 95% confidence interval (95% CI): 0.023-0.487], nonporous (P=0.046; HR =0.209; 95% CI: 0.045-0.971), and negative AR expression (P=0.042; HR =1.223; 95% CI: 0.049-1.012). The AR-positive TNBC patients had better disease-free survival (DFS) than the AR-negative TNBC patients 2-5 years after surgery (P<0.05). TCM was an effective treatment for TNBC (P<0.001; HR =51.682; 95% CI: 6.660-401.025). In the AR-negative group, patients who received the TCM treatment tended to have a better DFS than those who did not receive the TCM treatment (P<0.001; HR =34.832; 95% CI: 4.448-272.756); however, no such difference was found in the AR-positive group. Conclusions: The TNBC patients with positive AR tended to have a low expression of Ki-67 and a better prognosis than AR negative TNBC patients. TCM is an effective treatment and has slight side effects.
