aValues are presented as No. (%).
bSensory block was recorded as “yes” with pinprick score ≤ 1 or “no” with pinprick test score of 2.
cMotor block was recorded as “yes” or “no” based on a motor test score of ≤ 1 or ≥ 2. Unable to assess postoperative motor block due to presence of sling on arm.
dP Values are based on two-tailed Fisher’s exact test.
