Their analysis showed a strong global longitudinal strain (GLS) correlation (r\u2009=\u20090.793, P\u2009&lt;\u20090.001) and explicitly cautioned against treating the two modalities as interchangeable for individual or longitudinal assessment. We support these conclusions and write to extend two methodological points. First, the 17 segment-level paired comparisons in Table\u00a04 are reported without explicit multiplicity adjustment. On recomputation against a Bonferroni threshold of \u03b1\/17\u22480.00294, 11 of 17 segmental differences remain statistically significant, indicating that the original segmental signal is more statistically robust than an unadjusted reader might assume; we therefore recommend explicit reporting of adjusted P-values together with a unified mixed-effects formulation that accommodates within-patient segment-to-segment correlation. Second, the GLS limits of agreement span 8.3 percentage points (\u2212\u20093.2% to\u2009+\u20095.1%), a width sufficient to misclassify individual patients across established GLS thresholds. A worked example is provided, and the recommendation to confine longitudinal follow-up to a single platform is argued to deserve more prominent placement in the Abstract and Conclusions.<\/jats:p>","DOI":"10.1186\/s44348-026-00076-7","type":"journal-article","created":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T02:29:03Z","timestamp":1781231343000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Segmental strain in chronic ischemic cardiomyopathy: clarifying the role of multiple-comparison adjustment and the clinical interpretation of limits of agreement"],"prefix":"10.1186","volume":"34","author":[{"given":"Maajid Mohi Ud Din","family":"Malik","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajesh Prasad","family":"Jayaswal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,6,12]]},"reference":[{"key":"76_CR1","doi-asserted-by":"publisher","DOI":"10.1186\/s44348-026-00065-w","volume":"34","author":"SS Khidr","year":"2026","unstructured":"Khidr SS, Abdel-Galeel A, Abdellatif M, Hamdan A, Kishk YT.
