The likelihood ratio for the electrocardiographic criteria was also calculated. The assessment of reproducibility of the two methods used was made by three independent observers in different occasions, using Lin's concordance coefficient.
La razón de verosimilitud likelihood ratio para los criterios electrocardiográficos también se calculó, utilizándose para ello el coeficiente de concordancia de Lin.
A razão de verossimilhança likelihood ratio para os critérios eletrocardiográficos foi também calculada, utilizando-se para isso o coeficiente de concordância de Lin.
