Table 3 Comparison of the rate of decrease in vital sign between pre- and post-distraction among the four groups

From: The influence of various distractions prior to upper gastrointestinal endoscopy: a prospective randomized controlled study

Vital sign   Group P-value
Group 1 Group 2 Group 3 Group 4
P (/min) Mean -1.98a 1.50b 1.90b 6.92c <  0.001
SEM 0.61 0.37 0.35 0.54
SpO2 (%) Mean −0.14a −0.04a 0.12a -0.25a NS
SEM 0.12 0.15 0.09 0.15
SBP (mmHg) Mean 1.00a 6.77b 6.55bc 9.92c <  0.001
SEM 0.92 1.23 0.98 1.31
DBP (mmHg) Mean 1.51a 5.71b 4.77b 7.83c <  0.001
SEM 0.59 1.24 0.77 0.81
  1. DBP, diastolic blood pressure; P, pulse; SBP, systolic blood pressure; SEM, standard error of the mean; SpO2, peripheral blood oxygen saturation
  2. P-value is based on the Kruskal Wallis-test. Significance is at the 5% level. Post hoc pairwise comparison were conducted by Mann-Whitney U test with the Bonferroni correction; different letters indicated a significant difference at the 0.00833 (0.05/6) level
