Correlations between dimensions were explored using patient responses at follow-up (42 days after esophagectomy). Only significant correlations (at < 0.05) are reported. Correlations were classified as very weak (r = 0–0.2), weak (r = 0.2–0.4), moderate (r = 0.4–0.7), strong (r = 0.7–0.9) or very strong (r = 0.9–1.0)
