SOI, Sleep onset insomnia; SMI, sleep maintenance insomnia; EMA, early morning awakenings insomnia. Patients were divided into subgroups of insomnia symptoms. Symptoms are not exclusive; they can occur either as single symptom or in occurrence with other symptoms. Symptoms were assessed for two times: At begin of insomnia and current state. For comparisons over time, p was calculated with chi-square tests. Significance level was set at 0.05. Significant differences were highlighted.
