Survival analyses were conducted for each individual using Kaplan-Meier methods, and log-rank tests were used to compare Kaplan-Meier survival curves between groups. In order to test the robustness of the results, we conducted sensitivity analyses on the various data sets by: (I) all ...

Repeated measures analysis of variance (ANOVA), non-parametric Friedman, and Wilcoxon signed-rank tests made the comparison within the same patients. We used receiver operating characteristic (ROC) curves for the detection of sensitivity and specificity.ResultsPatients who developed ICU complications ...
The time to first SSE was assessed using a Kaplan-Meyer analysis and Log-rank test. The risk and factors of SSEs were analysed by the Cox regression model. The analyses were based on the data up to the primary analysis cut-off. A p-value < 0.05 was used as a threshold for ...
Based on the Kaplan–Meier curves for 1-year mortality, the log-rank test demonstrated that the MPV/platelet ratio was an independent risk factor for mortality in critically ill patients (p = 0.015). However, there were no significant differences in mortality between the tertiles of baseline...
The gene mutation is refers to the gene the molecular structure change, namely in the gene deaeration nucleotide order of rank has had the change, thus causes the genetic information the change.The gene mutation frequency is very low, but can produce the new gene, has the vital significance ...
Each patient condition was assessed by modified Rankin Scale.Results: Data was analyzed using SPSS version 26 software. Related-Samples Wilcoxon Signed Rank Test was applied. Mean and standard deviation were calculated. P value was taken less than or equal to 0.05 for significant differences (p ...
Parametric data was analysed with paired t-test, and for non-parametric data the Wilcoxon signed-rank test and the Mann-Whitney U test were used. Correlations were scrutinised with the Kendall's tau coefficient. Results 13.2% of patients have had a total knee arthroplasty (TKA) at the time...
