1 · What the graph read from it

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.

2 · The registry

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

objectiveTo evaluate the feasibility and efficacy of the Quantitative-PRIMARY (Q-PRIMARY) model based on the PRIMARY score for diagnosing clinically significant prostate cancer (csPCa) using [18F]PSMA-1007 PET/CT.

methodsA total of 324 consecutive patients were prospectively enrolled and retrospectively analyzed. Cohort assignment was based on the availability of in-house multiparametric MRI: a training cohort (n = 222, no in-house MRI) and an internal validation cohort (n = 102, with in-house MRI). Histopathology from systematic 12-core biopsy or radical-prostatectomy specimens served as the reference standard. We developed the Q-PRIMARY model by integrating visual PRIMARY scores with quantitative SUV-based thresholds (ΔSUVpeak, SUVmax, SUVR) for each PRIMARY category (scores 2-4).

resultsThere were 27, 41, 33, and 46 patients in the four groups, with positive lesions found in 62%, 62%, 53.53%, and 65.08%, respectively. Optimal diagnostic parameters for csPCa included ΔSUVpeak, SUVmax, SUVratio (SUVR), and SUVmax. The areas under the curve (AUC) ranged from 0.888 to 0.944, with high sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The Q-PRIMARY demonstrates superior diagnostic accuracy and clinical benefits compared to MRI PI-RADS, with more stable performance in AUC (0.978 vs. 0.768), sensitivity (97.18% vs. 92.96%), specificity (96.77% vs. 54.84%), PPV (98.60% vs. 82.50%), NPV (93.70% vs. 77.30%), and clinical decision curve analysis (DCA).

conclusionIn this selected high-risk cohort, the [18F]PSMA-1007 PET/CT Q-PRIMARY framework delivered high diagnostic performance and complemented multiparametric MRI. External prospective validation is warranted before clinical adoption.
