**Table A1.** Comparison of baseline characteristics and treatment response between different subtypes of urethral sphincter dysfunction including dysfunctional voiding and poor relaxation of external sphincter.


B: before urethra botox injection, BOOI: bladder outlet obstruction index, BVE: bladder voiding efficiency, DO: detrusor overactivity, DV: dysfunctional voiding, FS: full sensation, FSF: first sensation of filling, P: post urethra botulinum toxin injection, PVR: post-void residual volume, PRES: poor relaxation of external sphincter, Qmax: maximal uroflow rate, US: urge sensation, VUDS: videourodynamic study. a Between-group differences after urethra botulinum toxin injection adjusting by the pre-treatment condition with Analysis of Covariance (ANCOVA). b Successful outcome was defined as global response assessment greater than mildly improve (score - 2). \* *p* < 0.05
