Data were expressed as mean ± standard deviation (SD) or median (first quartile, third quartile) depending on whether the normal distribution is being followed.
AC, adenocarcinoma; SCC, squamous cell carcinoma.
P < 0.05 indicates that the difference is statistically significant.
a
Comparisons were performed by Mann–Whitney U test.
b
Comparisons were performed by independent sample t-test.
