Pasw statistics version 19

The descriptive statistics of categorical variables, such as gender, education level, and year of diabetes diagnosis, are expressed as the frequency and percentage for each category. Continuous variables such as age, BMI, number of OHAs currently being taken, and blood sugar control status (A1C%, fasting blood sugar, abbreviate as glucose AC) are expressed in terms of the mean ± standard deviation (SD). Statistical analysis was performed using PASW Statistics Version 19.0 (SPSS, Chicago, IL, USA).

We analyzed statistically by using PASW Statistics version 19.0 (SPSS, Chicago, IL). All values are presented as mean ± standard deviation. We used Chi-square tests to compare the sex ratio. Intergroup comparisons were performed using unpaired t-tests. Partial correlation was used for adjusting for age and sex. We used Pearson’s product moment correlation coefficient to evaluate the correlation of the flow void areas overlying the pachyvessel against the entire flow void area in the choriocapillaris. A p value of < 0.05 was considered statistically significant.

Descriptive statistics are presented as number (percentage) or mean ± standard deviation (SD). For each cardiovascular outcome incidence rates, overall and stratified by sex, were calculated from the number of incident cardiovascular events and person-years at risk. To enable comparison between the cohorts, standardized rates were calculated, using the age and sex distribution in the GP cohort as standard. For the risk assessment age- and sex-adjusted hazard ratios (HRs) were calculated using Cox proportional hazard regression analyses. The largest SpA cohort – the PsA cohort – was used as the reference population in the comparison between the SpA cohorts. The proportional hazards assumption for the Cox regression analyses were evaluated graphically in survival curves and was considered fulfilled in all cases. Where applicable, 95% confidence intervals (CI) are reported. For incidence rates we have assumed a Poisson distribution when estimating 95% CI. Additionally, age- and sex-standardized prevalence and corresponding prevalence ratio (PR) with 95% CI for prior ACS, stroke, and VTE before start of follow-up were calculated for each SpA cohort, using the age and sex distribution in the GP cohort as standard/reference. Statistical analyses were performed by PASW Statistics version 19 (SPSS Inc., Chicago, IL, USA) and SAS Version 9.3 (SAS Institute Inc., Cary, NC, USA).

Statistical analysis was performed using PASW Statistics version 19 (SPSS Inc, Chicago, IL, USA) with the level of statistical significance set at P < 0.05. Comparisons among two groups were performed by Student's t test.
