Fridericia's formula showed the strongest reliability, indicating it as the preferred choice for QTc correction.
The Bazett formula performed worst with a correlation of r = 0.483, suggesting it may be less reliable than others.
Assessment included 22,063 ECGs from healthy individuals, enabling robust comparisons of QTc formulas.
Fridericia's formula remained the most accurate across different subgroups, implying broader applicability in clinical settings.
