Phyllodes Tumor: A Rare Cause of False-Positive Pregnancy Test Result.
Article in Cureus, 2025. 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
Phyllodes tumors (PT) are rare fibroepithelial neoplasms of the breast that are predominantly benign, but can exhibit malignant characteristics. Elevated beta-human chorionic gonadotropin (beta-hCG) levels, primarily associated with pregnancy and trophoblastic tumors, have been rarely reported in breast cancers and PT. We present a 28-year-old premenopausal female with a rapidly growing, painful mass in the right breast. Imaging and biopsy confirmed a malignant PT. Surprisingly, preoperative testing revealed a positive urine pregnancy test (UPT) and an elevated beta-hCG level (1,152.7 mlU/mL). After pregnancy was deemed unlikely, the patient proceeded with a right total mastectomy. Postoperatively, the beta-hCG level decreased, confirming tumor-related phenomenon. Pathology revealed malignant PT with liposarcomatous components and ductal carcinoma in situ (DCIS). The association between PT and elevated beta-hCG levels is exceptionally rare and poorly understood. This case highlights the importance of considering unusual presentations in PT patients.
