Recent studies suggest increased cardiovascular disease (CVD) risk after INSTI initiation, but findings remain inconsistent. The Swiss HIV Cohort Study is nationally representative, collects high-quality data, and provides an ideal setting for independent evaluation using causal methods, avoiding participant overlap in multicountry HIV-cohort consortiums.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We emulated sequential target trials from November 2011 to September 2025 to estimate the effect of switching from non-INSTI to INSTI-based treatment on 6-year CVD risk among treatment-experienced people with HIV. Eligible participants were \u226518 years old, INSTI-naive, virally suppressed, and without CVD history. For each trial, participants were assigned to remain on non-INSTI or switch to INSTI. Intention-to-treat (ITT) and per-protocol (PP) effects were estimated using pooled logistic regression with baseline adjustment (ITT) and inverse probability weighting (PP).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 8815 individuals contributing 539 017 person-trials, 5750 switched to INSTI, and 507 CVD events occurred. In ITT analyses, the adjusted risk ratio for switching versus remaining on non-INSTI was 1.34 (95% confidence interval 1.03\u20131.69) after 1 year, and 1.03 (0.88\u20131.16) after 6 years. Absolute risk differences were small, ranging from 0.20 percentage points (0.02\u20130.37) after 1 year to 0.13 (-0.49 to 0.58) after 6 years. Per-protocol estimates were similar.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Switching to INSTI-based treatment did not substantially increase long-term CVD risk in treatment-experienced individuals with well-controlled HIV.
