Introduction: Most of epidemiological researches, specifically, those studies not totally limited to the simple description; involve comparisons among groups by time of among studies. Even when the statistics is appropriately applied, results may be interpreted with difficulty by an inexperienced. This study was conducted to describe the use of statistic procedures in the original papers of the Cuban Journal of Hygiene and Epidemiology, quantifying the statistic accessibility for the readers. Methods: The papers published were analyzed in the section of Original Papers from 1996 to 2009, excluding the methodological researches, qualitative studies, bibliographic reviews and news selecting 180 original papers. The sections Methods and Results were studied in detail where we identified the analyses carried out to be classified in 14 hierarchic categories with three levels of accessibility (Emerson-Colditiz): descriptive statistic, bi-varied analyses and complex analyses including the multi-varied. Accessibility was defined like the ratio of accessible articles for readers with different levels of statistic knowledge. Results: The more frequent statistic procedures were: descriptive statistics (88.7 %), Chi2 (17.3 %), risk measures (18.7 %), t-Student test (7.3 %) and logistic regression (7.3 %). Overall, the 79 % of papers were accessible to a reader with basic knowledges (bi-variable analysis), figures similar to those of other biomedical journals. Conclusions: A significant percentage of original papers of the Cuban Journal of Hygiene and Epidemiology nowadays incorporate complicated analyses in its development. It is advisable that readers must to deepen in our statistic knowledges.
