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
backgroundPrognostic indicators based on the initial prostate-specific antigen (PSA) levels, nadir PSA, and time to PSA nadir were calculated to evaluate prognosis after primary androgen deprivation therapy (PADT), as these have been reported in very few studies. We attempted to evaluate the prognostic role of the slope associated with nadir PSA in patients treated with PADT.
methodsA total of 107 patients who were treated with PADT from 2015 to 2019 were reviewed. The Kaplan-Meier method and Cox regression model were used to analyze the prognostic significance of the slope associated with nadir PSA in predicting progression-free survival (PFS) and overall survival (OS).
resultsAfter PADT, the median follow-up duration was 40.1 months; 66 patients (61.7%) had disease progression, and 33 patients (30.8%) died. In the univariate analysis, T stage, N stage, nadir PSA, time to PSA nadir, nadir PSA declining slope (nPSA-DS), nadir PSA percentage declining slope (nPSA-PDS), and nadir PSA line slope (nPSA-LS) were significant predictors for PFS and OS. The multivariate analysis showed that a higher nPSA-DS (> - 0.74) and lower PSA nadir (≤0.16 ng/ml) were independent predictors for prolonged survival. The significance of nPSA-DS and nPSA was supported by the analysis of nPSA-DS and nPSA as time-dependent covariates. The combined analyses demonstrated that patients with a higher nPSA-DS and lower PSA nadir had the best PFS and OS.
conclusionsThe slope associated with the nadir PSA of nPSA-DS was a significant independent predictor for patients treated with PADT. Nadir PSA and nPSA-DS have a synergistic effect on prognosis.
