Frequency Survey of Brain Metastases and Its Associated Factors Among Iranian Women with Breast Cancer: A Cross-sectional Study in Tehran City.

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
backgroundBrain metastases are serious complication of breast cancer (BC) that poses a critical management challenge. Hence, this study aimed to evaluate clinical findings, the status of hormonal receptors, and their correlation with brain metastasis among patients with BC. MATERIALS AND
methodsThis cross-sectional study was performed on women with BC that was newly diagnosed with brain metastasis from 2020 to 2023. Also, hormonal receptor status (such as p53, estrogen receptor [ER], progesterone receptor [PR], human epidermal growth factor2 [HER2]), histopathological type of BC, duration of disease, type of treatment, local cerebral invasions, and initial presentations were recorded. A P-value less than 0.05 was considered as statistical significance.
resultsOf a total of 302 patients, 49 (16.2%) patients had brain metastasis. The mean age of patients was 45.21±8.3 years, which was significantly lower in patients with metastasis (45.96±11.31 vs. 51.13±12.61 years, P=0.008). There was a significant association between the duration of disease in patients with and without brain metastasis (2.76±1.03 vs. 5.55±3.32 years, P=0.002). Also, the most prevalent histopathological type of BC was invasive ductal carcinoma (IDC). Headache was the most common clinical presentation among patients with brain metastasis. In addition, the most and the least common positive receptors among patients with metastasis were Ki-67 (93.87%) and PR (55.1%), respectively. Compared to patients without metastasis, HER2-positive and P53-positive receptors were markedly associated with brain metastasis (P=0.03 and P=0.021, respectively). However, there was no significant association between treatment methods and metastasis status.
conclusionPatients with younger age, IDC, and positivity of HER2 and P53 receptors were at an increased risk of developing brain metastases.
