Kaplan-Meier survival curve and the log-rank test
were used for recipient survival analysis.
10 significance level using a stratified log-rank test
Survival curves (without adjustment) were plotted using the Kaplan--Meier method and compared between risk-stratification groups using the log-rank test
The log-rank test
showed a statistically significant difference between survival curves (chi-square=9.
Sensitivity analysis###KaplanMeier method, log-rank test
Formal testing between groups with the log-rank test
, however, showed that duration of delirium between groups was only marginally significant (chi-square 3.
ulcerans lesion were compared by using the Fisher exact test, and cumulative healing was compared by using the log-rank test
The survival curves were compared by the log-rank test
and the Cox proportional hazards model was used to analyze the effect of prognostic variables on survivals.
A log-rank test
was used to compare the survival curves between those who died prior to our arbitrary cut-off to the survival curve of those who died after our arbitrary cut-off.
Una vez calculados los IC 95%, se estimo la significancia estadistica mediante la prueba de log-rank test
There are expanded discussions on the relevant subjects of epistemic uncertainties, crossover designs, equivalence trials and studies, hazard functions, and the log-rank test
placebo at 2 years; this finding, determined by a log-rank test
, was statistically significant for all clinical fractures, nonvertebral fractures, and key nonvertebral fractures.
