Group 0 name Corresponds to the control (unexposed) group for case-control studies
Control (healthy group)
Group 1 name Corresponds to the case (exposed) group for case-control studies
OCD T0 (Baseline)
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Patients with Obsessive-compulsive disorder (OCD), which is a neuropsychiatric condition characterized by intrusive and unwanted thoughts (termed obsessions) and repetitive behaviors or mental acts (termed compulsions), which are carried out to at least partially alleviate the anxiety or distress brought on by the obsessions. Timepoint 0 was the baseline timepoint prior to three months of pharmacological treatment and cognitive behavioral therapy (referred to as T0).
Group 0 sample size Number of subjects in the control (unexposed) group
33
Group 1 sample size Number of subjects in the case (exposed) group
