Retention rates at 6, 12 and 24\u2009months were 90.4%, 80.0% and 67.8%, respectively. Reasons for discontinuation included primary inefficacy (48% of 54 cases), secondary inefficacy (41%) and skin\/mucosal intolerance (4%). Statistically significant factors (P\u2009&amp;lt;\u20090.05) influencing treatment persistence included sex, smoking, concurrent conventional synthetic DMARDs (csDMARDs), corticosteroid use, year of prescription and axial or enthesitic involvement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Approximately two-thirds of PsA patients treated with guselkumab remained on therapy after 2\u00a0years.
