We considered a two tailed value of P<0.05 to be statistically significant.
P values were two tailed, and values <0.05 were considered statistically significant.
All significance tests were two tailed, and values of p<0.05 were considered statistically significant.
Comparisons of cases and controls are presented as two tailed P values.
We considered two tailed P values <0.05 to be statistically significant.
We considered two tailed P values lower than 0.05 to be statistically significant.
All analyses were done with SAS software and using two tailed P values.
Publication bias was assessed for the main end points by visually examining for funnel plot asymmetry and quantified by using the Egger regression test to calculate two tailed P values.
§ Comparisons of AUC values were made between the CRP/Alb ratio and other inflammation-based prognostic factors using z test method, a two tailed P value <0.05 was considered statistically significant.
Statistical significance was defined by a two tailed P-value of 0.05.
