The phrase "age were analysed using" is not correct in written English.
It appears to be a fragment and lacks proper subject-verb agreement, as "age" is singular and should be paired with a singular verb.
Example: "The ages were analysed using statistical methods."
Alternatives: "ages were examined using" or "age data were assessed using".
The relationships between two variables, such as seizure frequency and age, were analysed using Pearson's correlation coefficient analysis.
Comparisons of skewed data (length of stay and age) were analysed using non-parametric Mann–Whitney and Kruskal Wallis methods.
Differences in patients' educational background, gender and age were analysed using logistic regression (with no formal education and male as reference groups; age was used as continues variable).
Age was analysed using Wilcoxon signed-rank test.
Size for gestational age was analysed using an internal standard (the distribution in controls).
Since there was significant over-dispersion, as denoted by the likelihood ratio test (p < 0.001), the association between the perceived knowledge on medical errors definition and age was analysed using the negative binomial model.
The distribution of miR-145 and miR-145 patients to Gleason score, clinical stage, serum PSA levels, DRE and patients' age was analysed using the χ and Fisher's exact tests.
Effects of age, sex, and race on PCNSL survival time within two selected age groups (0 49 years and 50+ years) were analysed using proportional hazards regression models (Hosmer et al, 2008).
The associations of diagnosed allergy (predictor variable) at the ages of 9 and 18 months, 3 and 5 years with definite self-reported allergy or asthma (dependent variable) at the ages of 12, 15 and 18 years were analysed using binary logistic regression with random intercept [ 21].
Difference in log-transformed parasite densities among age groups were analysed using a normal GEE model with exchangeable correlation structure and semi-robust variance estimator.
Due to small sample sizes, differences in test performance (categorical data) between age groups were analysed using Fisher's exact test.
