Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Area Under the Curve (AUC) of the Numeric Rating Scale at Rest (NRS-R) Pain Intensity Scores Through 72 Hours for Subjects Receiving SKY0402 vs. Placebo.	To assess pain intensity at rest (NRS-R), the subject was to assume a resting position that did not exacerbate his or her postoperative pain and respond to the following question: "On a scale of 0 to 10, where 0 = no pain and 10 = worst possible pain, how much pain are you having right now?"	72 hours	No
Secondary	Participants With Adverse Events Through 72 Hours or Serious Adverse Events Through 30 Days		30 days	Yes
