  1. Note: PPI prepulse inhibition, PSC-PPI perceived spatial co-location PPI, PSS-PPI, perceived spatial separation PPI. PANSS positive and negative syndrome scale. The control factors were gender, age, education, duration, recurrence times, onset age, cigarettes per day and neuroleptic chlorpromazine-equivalent dosage. No correlation was found between PPI and symptoms in total patients or in patients (PANSS Total < 60). * p < 0.05
