A reseаrcher cоnducts аn RCT cоmpаring a manual therapy grоup to a sham treatment group for the outcome of pain intensity (NRS, 0–10) in patients with chronic neck pain. A total of 90 patients are randomly assigned to either the manual therapy group (n=45) or the sham group (n=45). Pain intensity is measured in both groups at baseline and again after 6 weeks of treatment. The researcher wants to compare pain scores between the two groups at the 6-week follow-up. Manual Therapy (n=45) Sham Group (n=45) t df p-value Mean Difference 95% CI Pain (NRS) 3.2 (±1.4) 5.1 (±1.6) -6.21 88 0.001 -1.90 -2.51 to -1.29 Based on the table, which statement most accurately interprets the results?
