The means were compared with independent Student's t test.
All the tests were considered statistically significant at p < 0.05 and the means were compared using Turkey's multiple comparison test.
The data underwent repeated measures analysis of variance and the means were compared by Tukey׳s test (P≤0.05).
The statistical analyses were conducted using PROC MIXED from SAS, and the means were compared using Tukey's test (P<0.05).
All data were subjected to analysis of variance (Gomez and Gomez 1984), and the means were compared using "the least significant difference" (LSD) test at 0.05 probability level.
Using SPSS version 16, the data were statistically computed by one-way ANOVA, and the means were compared using Student's t test.
The differences among the means were compared by high-range statistical domain using Duncan's test with the standard software SPSS 16.0 version.
All data were subjected to one-way analysis of variance (ANOVA), and the means were compared for significance by the least significant difference (LSD) test at P < 0.05.
The data obtained were subjected to analysis of variance, and the means were compared with the Student-Newman-Keuls test (p < 0.05).
The data were submitted to the variance analysis and, when significant, the means were compared by the Tukey test (p < 0.05).
The data for PIR was analyzed using analysis of variance in a group balanced block design (Gomez and Gomez, 1984) and the means were compared by least significant difference (Steel and Torrie, 1982).
