Thromboembolic Events in Castration-Resistant Prostate Cancer Patients With and Without Cardiovascular Comorbidities Receiving Oral Androgen Receptor Pathway Inhibitors.

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
backgroundThis study investigates the association between thromboembolic events (TE) and castration-resistant prostate cancer (CRPC) patients receiving oral androgen receptor pathway inhibitors (ARPi) compared to those undergoing chemotherapy, both with and without a pre-existing history of cardiovascular disease (CVD).
methodsA total of 2779 men diagnosed with CRPC were identified using the Surveillance, Epidemiology, and End Results (SEER) Medicare Linked Database from 2012 to 2016. Patients were stratified based on their CVD history. Within each CVD stratum (pre-existing CVD vs. no pre-existing CVD), patients were further categorized into two treatment groups: those receiving oral ARPi and those undergoing chemotherapy. Unadjusted and inverse probability treatment weight (IPTW)-adjusted proportional hazards models, using Fine and Gray's method, were applied to evaluate the potential association between ARPi treatment and TE.
resultsPatients with pre-existing CVD treated with ARPi exhibited a significantly lower crude hazard ratio (HR) for TE compared to chemotherapy (HR 0.39, 95% CI 0.27-0.58, p < 0.001). However, after adjustment using IPTW, this association was no longer significant (adjusted hazard ratio [AHR] 1.00, 95% CI 0.75-1.32, p = 0.99). For patients without CVD, ARPi use was also associated with a reduced risk of TE in the crude analysis (HR 0.53, 95% CI 0.32-0.87, p = 0.01), but this effect was not statistically significant after IPTW adjustment (HR 0.99, 95% CI 0.69-1.41, p = 0.94).
conclusionARPi demonstrated no significant effect on TE risk compared to chemotherapy, regardless of pre-existing CVD status. Similarly, when excluding patients with a prior history of TE, ARPi use remained non-significantly associated with new TE in the IPTW-adjusted competing risk analysis, highlighting the need for further investigation.
