Study the relation of some biochemical parameters with a vitamin d deficiency in cardiovascular disease patient in Kirkuk city

As in any research work, this work also identified some limitations. One of the limitations was the fact that the groups were not homogeneous in terms of the proportion of men and women. The results were not treated according to gender for all variables because, for most of them, we would be working with a very small sample. If we had more women, we could have treated all the data according to gender and verified whether the variables studied had different behaviours between men and women. The differences between controls and patients could have been even greater. However, this is what has been done in most studies published to date. Perhaps this is a gap and studies should be developed in patients monitored over several years to, in a way, assess the role of vitamin D in the evolution and prognosis of these individuals. In the patient group, there were only 16 individuals with vitamin D sufficiency. If the sample had been larger, it is possible that we would have had a greater number of individuals with vitamin D sufficiency in this group and it would have been possible to make comparisons with a greater degree of reliability
