Although the trend components The overall average of the series which varies over time for almost all variables tabulated show statistical significance, the model is unstable once the slope is determined for each variable. There is one exception: duodenal peptic acid disease which had a negative significance for its slope of =βt-0.00090; p = 0.0233.
Si bien la componente tendencia media global de la serie que va variando a través del tiempo muestra significancia estadística para todas las variables allí tabuladas, el modelo no se sostiene una vez se determina la pendiente en cada una de ellas, a excepción de la enfermedad ácido péptica duodenal, cuya pendiente negativa resulta significativa βt= -0,00090; p = 0,0233.
