A fragility index analysis of clinical trials evaluating low-intensity extracorporeal shockwave therapy for erectile dysfunction. Int J Impot Res 2023:10.1038/s41443-023-00722-4. [PMID: 37296223 DOI: 10.1038/s41443-023-00722-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 05/23/2023] [Accepted: 06/01/2023] [Indexed: 06/12/2023]
Abstract
Erectile dysfunction is a common sexual dysfunction that affects a significant proportion of men. Low-intensity extracorporeal shockwave therapy has been evaluated in multiple clinical trials as a therapeutic option for men with erectile dysfunction. The robustness of these clinical trials is not well defined, as the trials are hindered by inconsistent treatment protocols, small study arm size and short follow-up intervals. The fragility index is a statistical analysis which is used to evaluate the robustness of clinical trials. It is calculated by evaluating the minimum number of patients in a given trial arm that would be required to have an alternative outcome to alter the statistical significance of the results. The lowest fragility index in statistically significant trials is 1, meaning that if just one participant experienced an alternate outcome, the results would no longer achieve statistical significance. The upper limit is determined by the number of participants in a given arm of the trial. Herein, a scoping review of clinical trials evaluating the efficacy of low-intensity extracorporeal shockwave therapy in erectile dysfunction to determine the fragility index of trials with clinically significant results. We hypothesized that the fragility index would be low, indicating the results are less robust and generalizable.
