Impact of endoscopy-based research on quality of life in healthy volunteers

Figure 2 Changes in different multiple dimensions and physical, mental and totals scores between baseline and end of study determined by SF-36. During the 6-mo study with cross-over design, 10 HV underwent a total of 150 endoscopic examinations and 4500 biopsies from the antrum, corpus and duodenal bulb. The results are expressed in mean ± SD. Dotted line shows the theoretical max score from 100. Significant changes were observed (^a) for general (84.4 ± 13.1 vs 79.4 ± 15.4, P = 0.023 paired t-test) and mental health (80.0 ± 6.8 vs 83.2 ± 7.5, P = 0.022 paired t-test). In the remaining dimensions, physical, mental and total scores P > 0.05.
