Table 1.
Population characteristics for controls and alcoholic patients with one (SDTx) or more (MDTx) previous detoxifications. Values given in mean (standard deviation) except for units drunk per day for which values reported are median (and range)
| Variable | Controls (n = 31) | SDTx (n = 17) | MDTx (n = 12) | Statistical analysis |
|---|---|---|---|---|
| Age (years) | 40.2 (8.7) | 37.6 (9.6) | 44.4 (9.5) | F(2,59) = 1.79, n.s. |
| Gender | 16M, 15F | 11M, 6F | 7M, 5F | χ2(2) = 0.78, P = 0.676 |
| Full scale IQ (from NART) | 106.7 (7.3) | 101.9 (7.1) | 106.3 (6.3) | F(2,59) = 2.62, n.s. |
| Supervised detoxificationsa | N/A | 1.3 ± 0.1 | 4.3 ± 0.4 | t(12.6) = −6.65, P < 0.001 |
| Cigarettes/day | 10.8 (4.0) | 24.6 (18.1) | 23.6 (8.2) | F(2,27) = 1.192, P = 0.169 |
| Alcohol unitsb drunk per day | 1.8 (0–9) | 28.0 (10–187.90) | 39.7 (20–150) | χ2(2) = 44.9, P < 0.001 |
a
Significant differences between SDTx and MDTx groups.
b
One unit = 8 g of alcohol (UK defined unit of alcohol). F = female; IQ = intelligence quotient; M = male; MDTx = multiple detoxification group; NART = National Adult Reading Test; N/A = not applicable; n.s. = not significant; SDTx = single detoxification group.
