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
backgroundOutcomes of metastatic castration-resistant prostate cancer (mCRPC) treated with androgen receptor signaling inhibitors (ARSIs) vary widely and may not be fully reflected by PSA and standard clinicopathologic factors. We evaluated the prognostic value of serum neuron-specific enolase (NSE) at baseline and early on-treatment dynamics.
methodsWe retrospectively analyzed ARSI-treated mCRPC patients with available baseline NSE (n = 120). NSE was dichotomized by the upper limit of normal (ULN, 12.5 ng/mL). Radiographic progression-free survival (rPFS) and overall survival (OS) were estimated by Kaplan-Meier methods and compared by log-rank test. Multivariable Cox models adjusted for age, baseline PSA (per 100 ng/mL), line of therapy (2-4 vs 1), Gleason score (> 7 vs ≤ 7), metastatic timing (synchronous vs metachronous), and visceral metastases (present vs absent). NSE dynamics were evaluated using a 28-day landmark approach among patients alive and at risk at day 28 with available baseline and week-4 NSE (rPFS landmark n = 47; OS landmark n = 48); follow-up was redefined from day 28 and dynamics were modeled as log2(NSE
resultsMedian follow-up was 44.7 months (95% CI 35.7-48.3). Baseline NSE > ULN was associated with shorter rPFS (9.4 vs 20.8 months) and OS (23.5 vs 38.2 months). In multivariable analyses, baseline NSE > ULN remained independently associated with inferior outcomes (rPFS HR 1.81, 95% CI 1.15-2.85, p = 0.011; OS HR 1.85, 95% CI 1.12-3.05, p = 0.017). In landmark models, higher NSE dynamics were independently associated with worse outcomes (rPFS HR 4.30, 95% CI 1.06-17.39, p = 0.041; OS HR 8.78, 95% CI 2.15-35.77, p = 0.002).
conclusionsIn ARSI-treated mCRPC, baseline NSE above ULN and early 4-week NSE dynamics provide independent prognostic information for rPFS and OS, supporting NSE as a pragmatic adjunct to clinical risk stratification.
