References of retrieved articles and relevant reviews were manually searched. We included observational studies or randomized trials reporting ICM use in patients with ESUS or cryptogenic stroke\/transient ischemic attack (TIA), providing data on AF detection rates and\/or timing metrics (stroke-to-ICM interval, ICM-to-AF interval). Two reviewers independently screened studies and extracted data. Disagreements were resolved by consensus or third-party adjudication. Data were extracted following Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Study-level AF detection rates were modeled using logit-transformed proportions and pooled using random-effects models (REML). Mixed-effects meta-regressions assessed the effect of timing (stroke-to-ICM interval) on AF detection and diagnostic delay, adjusting for ICM monitoring duration. The primary outcomes were pooled AF detection rate and mean time from ICM implantation to AF diagnosis. Timing of implantation was assessed as a continuous and categorical (early, intermediate, delayed) variable. Forty-seven studies (\n                      <jats:italic toggle=\"yes\">N<\/jats:italic>\n                      \u2009=\u20096918 patients) were included. The pooled AF detection rate was 27.3% (95% CI: 24.6\u201330.2), with substantial heterogeneity (\n                      <jats:italic toggle=\"yes\">I<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200980.8%). Early ICM implantation (&lt;31.5\u2009days from index event) was associated with a higher AF detection rate compared with delayed implantation (30.0% vs 23.7%;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.0017), independent of monitoring duration. Stratified meta-regression confirmed that delayed implantation was associated with lower AF detection even after adjusting for ICM duration. For each additional day of delay in ICM implantation, the time from AF diagnosis increased by an additional 0.32\u2009days on average, even after accounting for monitoring duration (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.0007).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>These findings suggest that earlier ICM implantation enhances AF detection after ESUS or cryptogenic stroke and shortens diagnostic delay.
