Dietary quality was assessed using a Diet Quality Index (DQI) incorporating processed meat, fish, and plant-based food consumption. Monocyte counts were measured at baseline. Cox proportional hazards models with restricted cubic splines were used to examine the dose\u2013response relationship between monocyte counts and CVD risk, stratified by dietary quality. Joint analyses evaluated combined effects of high monocyte counts and unhealthy diet on CVD outcomes. Proteome-wide interaction analysis was performed to identify plasma proteins linking diet-immune interactions to CVD risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      During a median follow-up of 16.2\u202fyears, 1,834 CVD events occurred. Elevated monocyte counts were associated with increased CVD risk (HR per SD: 1.28, 95% CI: 1.11\u20131.48,\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.0009).

Joint analysis revealed that participants with high monocyte counts and unhealthy diet faced the highest risk (HR: 1.18, 95% CI: 1.03\u20131.35), while those with high monocyte counts but healthy diet showed no excess risk (HR: 1.04, 95% CI: 0.91\u20131.20). In an exploratory proteome-wide interaction screen, Regenerating islet-derived protein 4 (REG4) was identified as the top nominal interaction signal (P interaction\u202f=\u202f2.69\u202f\u00d7\u202f10\n                      <jats:sup>\u22125<\/jats:sup>\n                      ; FDR q\u202f=\u202f0.079), though this did not survive multiple testing correction.
