Data were checked for normality and homogeneity of variances using SPPS Statistics version 20.0 (IBM Corp., Armonk, NY, USA). All data were then subjected to two-way analysis of variance (ANOVA) by SPPS. Mean differences in treatments were separated by LSD at p < 0.05. All data are presented as means ± standard error (S.E.) with n = 6.

A power analysis was calculated. Previous data regarding the prevalence of a levator avulsion after first vaginal birth have indicated a mean occurrence of approximately 25%. 5 Our hypothesis was that a mediolateral episiotomy reduced the risk of levator avulsion. We considered a difference of 20% to be clinically relevant. We assumed an alpha risk of 5% and a beta risk of 20% (ie, a power of 80%). With these criteria we needed at least 91 women in each group; therefore, we planned to include 100 women in both groups.
Statistical analysis was performed using IBM SPPS Statistics version 20.0. The comparison of means between groups was performed by the Student t test after For the logistic regression, we controlled for known risk or protective factors for occurrence of obstetric trauma like levator avulsion or obstetric anal sphincter trauma including maternal age, mediolateral episiotomy, duration of second stage of labor, fetal birthweight, and nonocciput anterior fetal head position. 5,28e30 For the study of categorical variables, Fisher exact and c 2 tests were used as appropriate. For ordinal data the Kruskal-Wallis test was used. A 2-sided value of P < .05 was considered to indicate statistical significance.

Statistical analyses were performed using IBM SPPS Statistics, version 20. A Kruskal–Wallis test with Dunn’s multiple comparisons adjustment was used to compare the markers between the study groups. The χ2 test was used for categorical variables.

Statistical analysis was performed using SPPS Statistics version 20 software (IBM, New York, NY, USA). The data were analysed by analysis of variance (ANOVA) and a post hoc Tukey test was performed when a significant difference was detected. A P-value of <0.05 was considered statistically significant. Based on data from previous studies 8, 9, 11, 12 , ten subjects were estimated to provide a power of 80% at a five percent significance level to detect a 20% difference in thromboelastometric parameters from control samples.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
