PRIMARY outcome

Timeframe: 0-1 hours post operatively

Population: Overall Number of Participants Analyzed is not consistent with numbers provided Participant Flow module due to patients refusing or being unable to provide the reading for outcome during the allocated time frame which could vary the number of results obtained in a specific time frame. The analysis was done and revised by our Statistician

Measured by the Numeric Pain Rating Scale (NRS) with a range of 0-10 where 0 represents No pain at all ( best outcome) and 10 represents Worst possible pain (worst outcome).

6-Minute walk distance (6MWD)-Defined as the distance in (m) an individual is able to walk a long a flat 30 m walkway over six--minute period, with breaks as required. walk testing has been validated in the obese population, clinically significant differences occur when distances of at least 80m occur. 0 m would be the worst possible value for this outcome and the higher the number achieved in the six-minute duration the better (Better outcome)
