Kaplan-Meier curves of the cumulative incidence of systolic blood pressure reduction and heart rate elevation from baseline.
a and c) Cumulative incidence of 20% reduction in systolic blood pressure from baseline in patients who underwent neurosurgery and urological surgery. b and d) Cumulative incidence of 20% elevation in heart rate from baseline in patients who underwent neurosurgery and urological surgery.
Abbreviations: Non-pretreated (Non), patients who had no pretreatment before surgery; 5-ALA-pretreated (5-ALA), patients pretreated with 5-aminolevulinic acid; NeuroSRG, neurosurgery (brain tumor resection); TUR, urological surgery (transurethral resection of bladder tumor); SBP, systolic blood pressure; HR, heart rate.
