Table 4 Reclassification cross-relations for diagnosis and grading of LV DD between using estimated and observed LAVI

From: Validation of evaluating left ventricular diastolic function with estimated left atrial volume from anteroposterior diameter

  Using observed LAVI
  Normal DF Grade I DD Grade II DD Grade III DD Indeterminate Total
Using estimated LAVI

 Grade I DD 0 23 1 0 0 24
 Grade II DD 0 9 20 0 4 33
 Grade III DD 0 0 0 17 0 17
 Indeterminate 7 0 3 0 19 29
