Studies in this group with the greatest areas below the ROC curve were those by NonJing Peng 2003 in which S and E= 100%, Peng 2005 in which S and E= 100%, Hino 2004 in which S and E= 100%, and Barriga 2004 in which S and E= 100%,13, 21-23. This is because the sensitivity and specificity of these studies were greater than 95%.
Con respecto a la curva ROC se observó, en este grupo, que los estudios que tienen mayor área bajo la curva son NonJing Peng 2003 S y E=%, Peng 2005 S y E=%, Hino 2004 S y E=%, Barriga 2004 S y E=% 13, 21-23; esto se debió a que la sensibilidad y especificidad de estos estudios eran mayores al 95%.
