Commentary on: Tiihonen J, Mittendorfer-Rutz E, Majak M, et al. Real-world effectiveness of antipsychotic treatments in a nationwide cohort of 29 823 patients with schizophrenia. JAMA Psychiatry 2017;74:686–693.

Presence or absence of superiority has recently been particularly controversial for clozapine and long-acting injectable antipsychotics (LAIs), triggered by contrasting positive, negative and inconsistent meta-analyses of randomised controlled trials (RCTs).
