Calculate the Relative Risk (RR) of Complications: In a study comparing two anesthetic techniques, 12 out of 100 patients using Technique A experience complications, while 24 out of 100 patients using Technique B do.Formula: RR = Risk in Technique A ÷ Risk in Technique B

Calculate the Relative Risk Reduction (RRR): If the Risk Ratio for an anesthetic intervention is 0.7, calculate the RRR. Convert to a percent. Enter a whole number only. Formula: RRR = (1 − Risk Ratio) × 100
