These markers included global longitudinal strain (GLS), circumferential strain (GCS), radial strain (GRS), early diastolic mitral annular velocity (e\u2032), ratio of mitral valve velocity and mitral annular velocity in early diastole (E\/e\u2032), left atrial reservoir strain (LASr), and left atrial volume index (LAVI). Standardized mean differences (SMD) and corresponding 95% confidence intervals (CIs) were pooled in overall and subgroup analyses. Additionally, publication bias, trim and fill analysis, sensitivity analysis including leave\u2010one\u2010out influence analysis, and meta\u2010regression were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Thirty\u2010four studies involving 1821 KD patients and 1157 healthy controls (HCs) were included.
