La media ± DE total de la máxima categoría alcanzada fue de 4,15 ± 4,61. Las tres categorías de análisis estadísticos utilizadas con más frecuencia en el total de los artículos fueron la categoría 1 (sólo descriptiva) en el 49,4%, pruebas t y z (categoría 2) en el 26,4% y tablas bivariables (categoría 3) en el 19,1%. Entre las categorías más complejas, las más utilizadas en todos los originales en conjunto fueron el análisis de la varianza (categoría 8) en el 9%, el análisis de supervivencia (categoría 16) en el 6,2%, y las correlaciones no paramétricas en el 3,4%. Al comparar por décadas se observa un descenso de la estadística sólo descriptiva del 74% en los años setenta, al 63,9% en los ochenta y al 36,1% en los noventa (90 frente a 80; p < 0,05; 90 frente a 70; p < 0,05; 80 frente a 70; p < 0,05). También se detectó un aumento del uso de las categorías 3 a 6 (p < 0,05), y entre de las más complejas aumentaron las categorías 8, 10, 11 y 16 (p < 0,05).

Among the more complex analytical categories, the most often used were analysis of variance (category 8) at 9%, survival analysis (category 16) at 6.2%, and non-parametric correlations at 3.4%. Comparing results by decade, the proportion of articles with only descriptive analysis fell from 74% in the seventies to 63.9% in the eighties and to 36.1% in the nineties (90s vs. 80s, p < 0.05; 90s vs. 70s, p < 0.05; 80s vs. 70s, p < 0.05). The use of statistics from categories 3 and 6 increased (p < 0.05), and the use of the more complex categories 8, 10, 11 and 16 increased (p < 0.05).
