The transit of oral premedication beyond the stomach in patients undergoing laparoscopic sleeve gastrectomy: a retrospective observational multicentre study

Table 3 The estimated lead times for patients whom premedication transited beyond the stomach

Proportions (%) of patients with transit of medication beyond the stomach	Estimated lead time (95%CI)
80	232 (180 ‒ 310)
85	250 (220 ‒ NA^a)
90	270 (245 ‒ NA^a)
95	310 (250 ‒ NA^a)
100	365 (NA ‒ NA^a)

^aThe upper value of the confidence interval for 85%–95% proportions cannot be calculated because of the sparse data in the last part of the lead time. Only four patients remained without determination (transit or non-transit of premedication) after 300 minutes
