Summary of (A) pain and (B) overall complications meta-analyses comparing Harmonic devices to conventional comparators. Mean difference is defined as (Harmonic value – comparator value) and relative risk is defined as (Harmonic value / comparator value) . The n-values are n patients included. Asterisks (*) indicate a significant association (p < 0.05). Abbreviations: OR odds ratio, RR relative risk, VAS visual analogue scale
