Real-world clinical outcomes of apalutamide versus abiraterone with androgen deprivation therapy for metastatic hormone-sensitive prostate cancer.

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
backgroundMetastatic hormone-sensitive prostate cancer (mHSPC) is an aggressive disease with a poor prognosis. Current treatment guidelines recommend combining androgen receptor axis-targeted therapies (ARATs) with androgen deprivation therapy (ADT) for mHSPC. While individual ARATs have shown success, few studies directly compare their effects.
aimTo compare the safety and clinical outcomes of abiraterone acetate (abiraterone) and apalutamide in chemotherapy-naïve mHSPC patients, focusing on prostate-specific antigen (PSA) kinetics, safety, and survival outcomes.
methodA retrospective, single-centre study included 107 chemotherapy-naïve mHSPC patients treated with abiraterone or apalutamide plus ADT. PSA levels were measured at baseline and during treatment. Primary outcomes were PSA progression-free survival (PSA-PFS) and overall survival (OS). Adverse events were recorded. Inverse probability treatment weighting adjusted baseline differences.
resultsMedian PSA-PFS significantly favoured apalutamide (log-rank p = 0.015). Achieving PSA ≤ 0.02 ng/mL was strongly associated with delayed progression (HR 0.07, 95% CI 0.02-0.28; p < 0.001). OS did not differ significantly between groups (p = 0.504). Apalutamide achieved lower median nadir PSA (0.02 ng/mL vs. 0.23 ng/mL, p < 0.001) and shorter mean time to nadir (4.5 vs. 7.2 months, p = 0.001), with more patients reaching ultralow PSA levels (≤ 0.02 ng/mL) during follow-up. Adverse events occurred more frequently with apalutamide (71.2% vs. 46.5%, p = 0.015), with fatigue and rash being the most common.
conclusionApalutamide demonstrated deeper and more sustained PSA reductions, translating into delayed disease progression compared to abiraterone. Both treatments were generally well tolerated, though adverse events were more prevalent with apalutamide.
