Remission Depth in Metastatic Hormone-Sensitive Prostate Cancer Is Associated With Prognosis in Patients With Initial Prostate-Specific Antigen Values Above 100 Ng/ML.

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
introductionRecently, new drugs have caused a paradigm shift in the treatment of metastatic hormone-sensitive prostate cancer (HSPC). Meanwhile, research has identified several prognostic factors of metastatic HSPC.
objectiveThe present study focused on remission depth in metastatic HSPC and evaluated its association with remission depth.
methodWe analyzed 427 patients diagnosed with metastatic HSPC with serum initial prostate-specific antigen (PSA) > 100 ng/ml. The nadir serum PSA value was used as a marker of remission depth for each duration to castration resistance by using receiver operating characteristic (ROC) curves. Cox proportional hazards regression was used to assess for any correlation of progression-free survival (PFS) and overall survival (OS) with the nadir PSA level.
resultsThe cut-off value for the nadir PSA level per time to castration resistance (TTCR) at three, five, seven, and nine years was calculated. The nadir PSA value alone was able to predict prognosis because of its high sensitivity, high specificity, and high AUC in ROC analysis. The nadir PSA level can be an independent prognostic marker not only for TTCR but also for OS on multivariate analysis.
conclusionWe identified the cut-off value for nadir PSA per TTCR period in patients with metastatic HSPC. The nadir PSA value alone can predict prognosis; this demonstrates utility in routine clinical practice due to its simplicity and accuracy.
