Each comparison between HRM and line tracings was statistically significant at both evaluations.
↵* p<0.01 for decline in diagnostic accuracy compared with first evaluation.
↵† p<0.001 for increment in diagnostic accuracy compared with first evaluation.
HRM, high resolution manometry; LES, lower oesophageal sphincter.
