From My Point Of View, For Example, First

From my point of view, for example, first of all Interpretation of causal dependence between the malignant is important Diseases and other illnesses which reveals set Potential sources of errors. So the first row of diseases (the small list) at Patients it is displaced to obvious positive association of these conditions (For example, a syndrome of Segrena, system red and system Sclerosis, etc.). The second row of diseases, more often when patients Get to hospitals show criteria Bradford'a and it is possible to present, As primary rheumatic diseases and malignant conditions Correlate much more strongly, than in a lump of patients. Correlation between these two conditions can Also to occur and it is casual, but it can reflect and causal Relations. For an estimation of causal relations between cancer and Rheumatic diseases, without force of association by criteria Bradford'a It is possible to estimate additional features. Criteria Bradford'a include the following elements The analysis: (1) demonstration of strong association between the causal agent and Result; (2) sequence of results with the list of sites Researches and them ; (3) demonstration of specificity of the reasons or The agent in known terms and results; (4) demonstration Corresponding variables of time sequence thus, That the reason (agent) always were or have occurred to result; (5) Demonstration of a biological gradient, in which quantity The reasons or agents conducts to less significant result; (6) demonstration Such biological explanation which makes sense for the agent Leading to obvious result; (7) thus co-ordinated The sequence of results is that that the argument of the reason is caused Also is familiar and known; (8) experimental certificates And certificates of similar conditions will well be co-ordinated.
