Table 2.
The Mini-mental State Examination (MMSE) scores of the patients
time point | group P (n = 30) | group C (n = 30) | Difference in means (95% CI) | P-value | |
---|---|---|---|---|---|
MMSE | 1 day preoperatively | 27.7 ± 2. 1 | 27.5 ± 2.2 | 0.2 (-0.9 to 1.3) | 0.719 |
7 days postoperatively | 27.0 ± 1.8# | 26.1 ± 1.7* | 0.9 (0.1 to 1.9) | 0.034 |
The data are represented as the mean ± SD
MMSE = Mini-Mental State Examination
Compared with group C, #P < 0.05; compared with 1 day preoperatively, *P < 0.05
Data were compared by repeated-measures analysis of variance
