Trial Outcomes & Findings for Pain Increases After Shoulder Injection (NCT NCT05438277)

NCT ID: NCT05438277

Last Updated: 2023-03-07

Results Overview

A flare reaction was defined as an increase of two or more points of Visual Analog Score (VAS) score during the first week following injection. The VAS is a patient reported pain score from zero to ten where zero is no pain and ten is the most pain.

Participant Flow

421 patients were enrolled in the study. Out of these 421, 15 patients received bilateral shoulder injections. Thus, there were 436 total shoulders injected. The term used in the study to refer to the number of shoulders injected, rather than the number of patients, is "person-visits."

Unit of analysis: Person-visits

PRIMARY outcome

Timeframe: Post-injection day 1 through 7

Population: The "Overall Number of Participants Analyzed" here reflects the number of person-visits for which data was able to be acquired. 16 person-visits in the MPA cohort were lost to follow-up during this time point, while 28 person-visits in the TA cohort were lost to follow-up during this time point. Loss to follow-up primarily was due to failure by subjects to mail their "home diary" VAS log.

A flare reaction was defined as an increase of two or more points of Visual Analog Score (VAS) score during the first week following injection. The VAS is a patient reported pain score from zero to ten where zero is no pain and ten is the most pain.
