The incremental prognostic value of quantifying LGE volume or mass beyond its mere presence, however, remains unresolved. The aim was to evaluate whether LGE quantification improves the prediction of SCD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>PubMed, Embase, and Web of Science were searched on 20 November 2024 for observational studies that related quantified LGE burden to ventricular arrhythmia (VA)\/SCD in NICM. Forty-one studies met prespecified criteria. Hazard ratios (HRs) were pooled with random-effects models, and quantification information was depicted in figures. Presence of any LGE was associated with a three-fold increase in VA\/SCD risk (pooled HR 3.31, 95% confidence interval: 2.58\u20134.24). Beyond this binary marker, every additional 1% (or 1\u2005g) of LGE was associated with a 12% relative risk increase (range 10\u201320%), independent of left ventricular ejection fraction and consistent across eight semi-automated thresholding techniques. This included 2\u20136 standard deviations above the reference myocardium and the full-width half-maximum method. Additionally, results were prone to substantial methodological heterogeneity (\u03c4\u00b2 = 1.49) and small-study bias. Once the presence of LGE was accounted for, scar quantification and location conferred minimal additional prognostic value.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Quantitative LGE assessment provides little incremental prognostic utility over dichotomous LGE detection.
