50	10.2 ± 4.1	10.7 ± 3.8
60a	11.5 ± 3.3	12.3 ± 3.4
70	14.6 ± 3.3	15.1 ± 3.6
Motility
RAC1	65 (42.5)	88 (57.5)
IAC	10 (6.8)	9 (6.4)

Absent2	63 (42.9)	38 (27.0)

¹Odds ratio (OR) = 0.4 (95%CI: 0.3-0.8) for having recurrent antegrade contracts (adjusted for procedure indication, patient opioid use and balloon used).

²OR = 2.4 (95%CI: 1.3-4.4) for having absent motility (adjusted for procedure indication, patient opioid use and balloon used).

^aP = 0.05, indicates a statistically significant difference between groups (adjusted for indication and patient opioid use).

DI: Distensibility index; RAC: Recurrent antegrade contracts: IAC: Isolated antegrade contractions: RC: Retrograde contractions.
