Modified Thoracoabdominal Nerves Block Through the Perichondrial Approach vs Subcostal Transversus Abdominis Plane Block for Postoperative Recovery After Laparoscopic Cholecystectomy: A Prospective, Randomized Clinical Trial.

For passive NRS, an unadjusted analysis suggested a nonsignificant trend favoring group M for the 24–0 hour change (Hodges-Lehmann median difference: 1; 95% CI: 0–2; P = 0.013); statistical significance was lost once Holm correction was applied (adjusted P = 0.052).
