Inconsistent selection of outcomes and measurement devices found in shoulder arthroplasty research: A systematic review

A ClinicalTrials.gov search was conducted and yielded 100 results. Articles meeting inclusion criteria were coded on the following characteristics: start date of trial, study status, study type, type of arthroplasty, sample size, measured outcomes, outcome measurement device, specific metric of measurement, method of aggregation, and outcome classification, and whether the outcome was considered a side effect/harmful.
