On statistical analysis methods improving epidemiological studies
MetadataShow full item record
Nowadays almost all the principles of diagnosis and treatment are determined by the statistical analysis of the observations made by practitioners. The analysis of medical data is therefore one of the most important elements that aﬀect the level of modern medical care. The research described in this paper aims to determine the characteristics of cardiac parameters in healthy children and in children with a diagnosis in arterial hypertension. Studies include children in the Lodz region. The purpose of the analysis is to determine risk factors of arterial hypertension and thus early diagnosis of children and as quickly as possible the inclusion of an appropriate treatment or observation. The analysis applies a number of methods, including descriptive analysis, grouping and statistical inference. The choice of methods is consistent with the requirements of the USMLE (The United States Medical Licensing Examination) and depends on the evaluated parameters. The research is carried out using professional statistical packages and the computer system designed and developed for this study. The use this system allows for the continuous process of research staging of new cases, which is a deﬁnite advantage when conducting epidemiological studies.
