Table 4 Comparison of adverse events between groups before and after propensity score matching.
| Variable | Before matching | After matching | ||||
|---|---|---|---|---|---|---|
| Group I (n=66) | Group S (n=95) | P-value | Group I (n=58) | Group S (n=58) | P-value | |
| Hypertension, n (%)1 | 28 (42.4) | 38 (0.40) | 0.758 | 24 (41.4) | 25 (43.1) | 0.851 |
| Hypotension, n (%)2 | 21 (31.8) | 21 (22.1) | 0.167 | 18 (31.0) | 12 (20.7) | 0.203 |
| Blood transfusion, n (%)3 | 7 (10.6) | 13 (13.7) | 0.560 | 6 (10.3) | 6 (10.3) | 1.000 |
| ICU admission, n (%) | 1 (1.5) | 4 (4.2) | 0.649 | 1 (1.7) | 3 (5.2) | 0.618 |
| Second surgery, n (%) | 1 (1.5) | 0 (0) | 0.410 | 1 (1.7) | 0 (0) | 1.000 |
| In-hospital mortality, n (%) | 1 (1.5) | 1 (1.1) | 1.000 | 1 (1.7) | 1 (1.7) | 1.000 |
| Awareness, n (%) | 1 (1.5) | 0 (0) | 0.410 | 0 (0) | 0 (0) | 1.000 |
| Values are expressed as mean±standard deviation or number of patients (n, %). Groups: I, BIS indices maintained at about 10 less than the BIS value at LOC; S, BIS indices maintained at 40–60. ICU – Intensive Care Unit; BIS – bispectral index; LOC – loss of consciousness. 1 Hypertension: use of any vasodilator during surgery to maintain systolic blood pressure no more than 140 mmHg; 2 Hypotension: use of any vasopressor during surgery to maintain systolic blood pressure no less than 90 mmHg; 3 Blood transfusion: the number of patients receiving blood transfusion during surgery and/or after surgery. | ||||||
