1 · What the graph read from it

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.

2 · The registry

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

objectivesDifferences in tumor biology, ethnicities, and healthcare structures across populations may contribute to variability in oncologic outcomes. This study compared baseline characteristics and oncologic outcomes of Japanese and German metastatic hormone-sensitive prostate cancer (mHSPC) patients.

methodsA pooled analysis of 1 215 mHSPC patients from Japan (JIKEI-YAYOI database, n = 639) and Germany (FRAMCAP database, n = 576) undergoing combination therapies between 2015 and 2025 was performed. Cox regression models were used to evaluate time to castration-resistant prostate cancer (ttCRPC) and overall survival (OS). Propensity score matched analyses (PSM) validation was performed.

resultsJapanese patients were older at diagnosis (median 73 vs. 70 years) and had higher PSA at mHSPC diagnosis (260 vs. 43 ng/mL). Moreover, Japanese patients had more frequently synchronous mHSPC (95% vs. 75%), high-volume disease (78% vs. 54%), and visceral metastases (16% vs. 8%). ADT plus androgen receptor pathway inhibitors (ARPI) was used more frequently in Japan (76% vs. 71%), as was the combination of ADT + ARPI + docetaxel (17% vs. 11%). Conversely, ADT + docetaxel was less commonly used in Japan (7% vs. 19%). Median ttCRPC was 39 vs. 23 months, and median OS was 80 vs. 51 months (Japan vs. Germany). After adjustment for relevant clinical covariates, Japanese cohort affiliation remained an independent predictor of prolonged ttCRPC (HR 0.53, p < 0.001) and improved OS (HR 0.54, p < 0.001). PSM analyses confirmed similar findings.

conclusionsDespite presenting with more adverse baseline characteristics, Japanese mHSPC patients demonstrated longer ttCRPC and improved OS compared with patients in Germany. These differences may reflect not only potential biological variations but also differences in treatment strategies and healthcare structures.
