An analytic study of cases and controls was carried out, in order to evaluate the usefulness of the statistical analysis involved in the identification of risk factors in patients with lung neoplasia, assisted in "Conrado Benítez García" and "Dr. Juan Bruno Zayas Alfonso" hospitals in Santiago de Cuba, from July 1st, 2012 to June 31st, 2013. Fifty cases were selected by means of a random systematic sampling and the same quantity of controls according to sampling through conglomerates in 4 stages (1:1). Logistical regression techniques and the statistical analysis were compared; the first one was used as keystone and sensibility, specificity, reasons of verisimilitude and index of Kappa were obtained, between them. It is concluded that both techniques are supplemented in the identification of risk factors and they allow a more complete interpretation of the causality phenomenon

Keywords : involved statistical analysis; lung cancer; risk factor; logistical regression; sensibility; specificity; secondary health care.
