Log-normal model is the best fitted model for duration from chest pain to coronary artery disease diagnosis: An outcome of retrospective cross sectional study

Cox proportional hazard model is the widely used technique for studying duration data. however,studies showed parametric modeling yields better estimation; though these models are less used due to their complicated application and interpretation. alongside,the duration from chronic chest pain to the diagnosis of coronary artery disease has not evaluated in the literature. therefore,this research investigated application of parametric modeling on the current duration while studying outcome from cross-sectional study. akaike information criteria was used to adjudicate different duration models.
