First, Shapiro-Wilks’ tests was used to verify if data are normally distributed. To compare socio-demographic data between VPT, FT groups and dropout participants, we used Student’s t-tests for normally-distributed and numeric data, and χ2 tests for nominal data. Considering that neonatal da...
We assumed an effective sample size of 1200 monitoring visits because multiple monitoring visits by 1 participant did not represent independent observations, thereby diluting the nominal power to discriminate test performance. This effective sample size would have had 90% power to detect a difference ...
These data show that, against the background of smoking, there is no difference for the patient between monotherapy and combined therapy. However, for the group of patients who quit smoking, combined therapy (LABA / LAMA) was more effective than monotherapy (LAMA) both on spirometry (26% and...
Also, classify its scale as nominal, ordinal, interval or ratio. 8.5. The following data represents the ages of 21 students in a class: 22, 24, 19, 17, 20, 27, 24, 23, 26, 17, 19, 22, 25, 22, 22, 21, 21, ...
For all nominal variables, absolute frequencies and percentages were calculated and baseline differences between the groups were assessed using a Chi-square test. The socioeconomic ordinal variable baseline differences between the groups were evaluated using the Mann-Whitney test. To compare mortality ...

Excluded patients: transferred patients, patients with missing info on sex, age, or symptomatic presentation, and patients with secondary diagnosis of ...
The seven acetabular variables used as age-related traits were substantially described, depicted, and evaluated by San-Millán et al. [34]. To evaluate the intra- and inter-observer error, weighted kappa statistic tests for ordinal data were performed [77,78,79]. The acetabular variables were ...

Then, crosstabs and the chi-squared test were used to study the association between perceived age discrimination and its possible antecedents in the case of nominal- and ordinal-level variables: socioeconomic, demographic, and health-related variables, as suggested by the existing literature on the ...
