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
purposeWe aimed to describe treatment patterns of patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) who progressed after receiving darolutamide in a real-world setting, and according to the standard clinical practice in Spain.
methodsThis was a multicenter, observational, retrospective study conducted at the urology and oncology departments of 17 Spanish hospitals that participated in the ARAMIS trial and its rollover study.
results85 patients, with a median age of 76 years, were included in the study. 49 patients (57.6%) progressed to mCRPC, with metastases located mainly in bone. Only 35 of them (71.4%) received at least one subsequent therapy. The most common first-line treatments after darolutamide were abiraterone (n = 22, 63%) and docetaxel (n = 10, 29%), with a median (IQR) treatment duration of 7.6 months (4.7, 12.7) and 4.8 months (3.8, 5.8), respectively; besides, the most frequent first-line/second-line treatment sequences were abiraterone-docetaxel and docetaxel-cabazitaxel. In addition, only 20% of patients with bone metastases received osteoclast-targeted therapy.
conclusionThese real-world practice patterns suggest a lack of consensus in Spanish clinical practice for the management of patients with mCRPC, indicating that there is a need for more standardized strategies and unification of the criteria to make decisions in accordance with the recommendations of international clinical practice guidelines.
