Generalised linear mixed models are an appropriate statistical method and, depending on the specifications within the model, can be used for normally distributed data (linear mixed models), binary, ordinal or categorical data (nonlinear mixed models) to investigate changes over time and the moderation...

First, positions were recoded to numerical categorical variables, then dummy variables were used for each position (1 if present and 0 if not present). Gender was also recoded the same way (men = 0 and women = 1). Age groups were categorised into an ordinal variable i.e. 20–24 years...
The aim is to obtain a multidimensional description of the structural properties of the ROIs. The MSN is then built considering the ROIs as nodes and modelling connection strength as the correlation between pairs of ROI vectors, thus integrating in a single connectome the ensemble of imaging ...
or the Wilcoxon rank-sum test (non-normally distributed). Three or more groups of continuous variables comparison was conducted by either the ANOVA (normally distributed) or the Kruskal–Wallis test (non-normally distributed). Categorical variables were compared using chi-square statistic tests or ...
(ANOVA) with Scheffe’s post hoc analysis. The categorical variables were compared using a chi-square test. The measurement values before and during the standardized Valsalva maneuver were compared using a paired t-test. The generalized linear model was used to investigate the influence of several...
In Germany, immunization against human papillomaviruses (HPV) is free of charge for all females aged 12 to 17 years. Since HPV infection rates rise soon after first intercourse, immunization against HPV should be completed before sexual debut. Knowledge of country-specific data on age at first in...
SA was used as numerical and categorical variable classified in three different categories according to the difference between SA and chronological age: late, on time or early maturers. On time when the difference was within ± 1.0 year of chronological age; late maturers when SA is less ...
Distributions of categorical variables were examined by Fisher's exact test. Odds ratios of clinical pregnancy, VP, and delivery were obtained for each group by logistic regression analyses, having the most desirable condition group (age 1 and BL-1) as the reference. Trend tests were performed ...
The analysed data set consisted of 1,581 variables (683 numerical and 898 categorical). A complete data set was not available for all participants included in SLAS-2, which is discussed in more detail below. We used a minimum spanning tree (MST) network derived from a pairwise effect-size...
