Survivors were more than nonsurvivors and had completed more long-distance working races. Survivors were also more likely to experienced a primary care doctor and founded atherosclerotic cardiac risk factors before the cardiac arrest. The strongest predictors of survival of cardiac arrest had been initiation of bystander-administered cardiopulmonary resuscitation and an underlying analysis other than hypertrophic cardiomyopathy . In a multivariate logistic-regression model in which these two factors had to be excluded due to perfect prediction, factors that were independently associated with survival of cardiac arrest were an initial cardiac rhythm of ventricular fibrillation or tachycardia and the amount of previous long-distance working races completed .PFGE patterns were analyzed with the use of BioNumerics software, version 5.10 and grouped into pulsed-field types by using Dice coefficient analysis and UPGMA clustering. An 80 percent similarity threshold was used to assign UNITED STATES PFGE types.17 Isolates also underwent polymerase-chain-response assay to detect the presence of tcdA, tcdB, and binary toxin genes and a subset of the very most common NAP types underwent PCR ribotyping.18 Between 2011 and January 2012 November, all laboratories serving the surveillance people were surveyed to assess the kind of C. Difficile diagnostic tests which were used during 2011.19 Laboratory surveys were used to estimate the proportion of cases in the surveillance areas which were identified by way of NAAT. Statistical Analysis Data were analyzed by using SAS software, version 9.3 .
