A random-effects model was used to pool risk ratios (RRs) and predictive performance metrics.

The meta-analysis indicated that PALS and LASr measured before treatment were effective predictors for AF recurrence. Analyzed as categorical variables, both a higher PALS (RR = 0.08, 95% CI: 0.04\u20130.16) and a higher LASr (RR = 0.91, 95% CI: 0.86\u20130.96) were linked to a significantly lower risk of AF relapse. Treated as continuous variables, a 1-unit increase in PALS (RR = 0.88, 95% CI: 0.85\u20130.91) or LASr (RR = 0.93, 95% CI: 0.88\u20130.99) was associated with a pronounced lower risk of AF recurrence. The pooled AUC values for PALS and LASr were 0.75 and 0.78, respectively. The predictive power of other parameters was limited or unclear: LASct and LAScd measured before treatment, as well as LASr measured after treatment (either as a categorical variable or a continuous variable), failed to show significant predictive power (all\n                      <jats:italic>P<\/jats:italic>\n                      &amp;gt; 0.05). Only for LASct measured after treatment as a continuous variable, each unit elevation in LASct was linked to a reduced risk of AF relapse (RR = 0.75, 95% CI: 0.63\u20130.91).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study suggests that lower PALS and LASr values are associated with a higher risk of AF recurrence.
