BACKGROUND: Case-control studies are useful for risk factors research, speacially for rare diseases or diseases with a prolonged latency period. OBJECTIVE: To identify the main characteristics of the case-control study, in order to reduce bias during the study evaluation and/or conduction. DESCRIPTION: This design is characterized by the selection of subjects with and without the event of interest and they are compared to identify risk factors in order to infer causal relationship, which is expressed, by odds ratio and 95% confidence intervals. CONCLUSIONS: Case-controls studies are a relatively easy and quick design to perform. However, it is susceptible to multiple sources of bias, which must be minimized to obtain greater reliability in the obtained inferences. [ABSTRACT FROM AUTHOR] |

ANTECEDENTES: los estudios de casos y controles son de utilidad cuando se buscan factores de riesgo para enfermedades poco comunes o que tienen un periodo de latencia prologado. OBJETIVO: identificar las principales características del estudio de casos y controles (Ca-Co) para favorecer la disminución de sesgos durante su evaluación o conducción. DESCRIPCIÓN: este diseño se caracteriza por la selección de sujetos con o sin el evento de interés. Éstos se comparan para identificar los factores de riesgo que favorecieron la presencia de este evento. La finalidad de este tipo de estudios es la de inferir una relación causal expresada mediante razón de momios y los intervalos de confianza al 95%. CONCLUSIONES: el diseño de Ca-CO es relativamente fácil y rápido de realizar. Sin embargo, es susceptible a múltiples fuentes de sesgo, las cuales deben de ser minimizadas para obtener mayor confiabilidad de las inferencias obtenidas. [ABSTRACT FROM AUTHOR] |
