From: Insomnia subtypes characterised by objective sleep duration and NREM spectral power and the effect of acute sleep restriction: an exploratory analysis

Figure 1

Short-sleeping and normal sleeping insomnia subtypes with delta-power deficiencies underestimate their total sleep time. Subjective sleep quality rating (A) and sleep state misperception (B) across insomnia subtypes and controls following the first night. The upper and lower whiskers indicate the value with Q3 + 1.5 × IQR and the value with Q1 − 1.5 × IQR, respectively. Black dots indicate outliers. SSDD short-sleep delta-deficient subtype, NSDD normal-sleep delta-deficient, NNS normal neurophysiological sleep subtype, *p < 0.05.
