Table 2 Comparison of selected sleep parameters: the parameters are based on time in bed (TIB), between controls and depressed patients (REM: rapid eye movement, REM-dens: REM-density, S2: stage 2, SOL: sleep onset latency, SWS: slow wave sleep, WASO: Wake after sleep onset).
depressed patients | controls | significance | |

SOL (min) | 15.7 ± 11.5 | 26.4 ± 25.0 | n.s. |
REM latency (min) | 97.3 ± 128.0 | 115.4 ± 90.0 | n.s. |
REM dens. (min-1) | 4.45 ± 1.66 | 4.46 ± 1.73 | n.s. |
REM (min) | 92.0 ± 46.2 | 77.9 ± 33.3 | n.s. |
S2 (min) | 202.6 ± 39.2 | 216.9 ± 59.0 | n.s. |
SWS (min) | 17.1 ± 12.7 | 34.1 ± 31.3 | n.s. |
WASO (min) | 91.4 ± 69.7 | 73.7 ± 79.8 | n.s. |
