Figure 1. Collection and Exclusion of Clinical Trials.

Figure 1

This figure depicts the process by which trials were collected from ClinicalTrials.gov. The initial search results were examined and studies that did not focus on treatments for OA pain were excluded. The included trials are further separated by the type of intervention they evaluate: pharmacologic, behavioral, surgical, or other.
