Probabilities of a pathological ⁶⁸Ga-PSMA-11 PET/CT scan (a) and plot of the rates of pathological PET/CT scans with confidence intervals (b) in relation to PSA levels in 971 patients. Blue columns Numbers of patients with a pathological PET/CT scan together with the rates which also represent the patient-based sensitivities of ⁶⁸Ga-PSMA-11 PET/CT in detecting recurrent PCa in relation to PSA level. Amongst all patients with a PSA level less than 0.2 ng/ml, 15 had values less than 0.1 ng/ml
