Table 2.

Time to spontaneous micturition, urine volume, and infusion volume in the two groups.

	EA group	Control group
N	31	28
Time to SM (min)^a	228 ± 78	313 ± 91^*
Urine volume (mL)^b	339 ± 109	361 ± 179
Infusion volume (mL)^b	1631 ± 270	1673 ± 303

Values are given as mean ± standard deviation. ^aDifference was analyzed by two-sample t-test between the two groups; ^bDifference was analyzed by Mann-Whitney U test between the two groups. ^* P < 0.001 versus EA group. EA: electroacupuncture; SM: spontaneous micturition.
