Limitations
A limited number of patients could be included in the study. Only the
evaluation of patients referred to the cardiology unit and all patients’
failure to come due to the Covid-19 pandemic process; patients included
in the study may not reflect the targeted population.
Considering the study groups’ basal characteristics, the differences in
diastolic blood pressure and triglyceride levels might affect the
investigation results, even if the relevant parameters are found in the
standard reference range. Similarly, vitamin B12 levels were within the
normal reference range in the patient group with and without insulin
resistance; it was significantly lower in patients with insulin
resistance than those without insulin resistance and control. This
difference may have affected the results.
