In the case of blood in stool, the variable \(OR\) = 14.454, (95% CI: 14.324 \(\div\) 14.658), which means that the phenomenon of bloody stools more often means UC than CD. The occurrence of bloody stools about 15 times increases the probability of ulcerative colitis. Similar results were obtained in the literature [32]. Current research, confirmed also by the analysis included in this work, returns the knowledge that this symptom is rare in CD, while the opposite is true for UC. The literature indicates that MCV levels change in IBD. However, the levels, functions, and causes of changes between UC and CD are still not well understood [33]. In the case of MCV, \(OR\) = 1.913 (95% CI: 1.899 \(\div\) 2.101), which means that increasing its value can cause the patient to be classified in the group with UC disease. Similar results were obtained for PLT (\(OR\) = 1.201, 95% CI: 1.199 \(\div\) 1.215). The PLT value may be increased if inflammation occurs. Both CD and UC are associated with abnormalities in the number and function of platelets. The role of platelet dysfunction in the pathogenesis of IBD is still unclear [34]. The obtained results indicate that the level is significantly higher in the UC group. Monocytes are part of the body's first line of defense, eliminating pathogens by phagocytosis or releasing a wide range of inflammatory mediators, such as cytokines, chemokines, and proteases. However, the roles and functions of monocytes in health and disease in IBD are not fully understood [15]. The differences in their levels are not confirmed. Because of the logistic regression, we got significant results indicating differences between UC and CD. The obtained odds ratio includes that the higher level of monocytes indicates UC (\(OR\) = 1.049, 95% CI: 1.039 \(\div\) 1.149). The conducted research emphasizes the role of eosinophils in the diagnosis of IBD, but there are no quantitative data between UC and CD. Our research indicates that the right parameter levels differ significantly in the analyzed groups [12]. Our study showed that it is significantly higher in the UC group (\(OR\) = 1.101, 95% CI: 1.002 \(\div\) 1.111). Our research indicates significant differences in basophil levels in the analyzed IBD groups. Literature indicates that their role and values in the course of diseases are not well known [16]. Logistic analysis concluded that the level of basophils is significantly higher in the UC group (\(OR\) = 2.118, 95% CI: 2.018 \(\div\) 2.128). In IBD, there are changes in the level of electrolytes. It is interesting to observe the differences in sodium and potassium levels in UC and CD [21]. Our study showed significant differences in them. Sodium has significantly higher levels in UC (\(OR\) = 1.162, 95% CI: 1.142 \(\div\) 1.182), while the same applied to potassium in CD (\(OR\) = 0.086, 95% CI: 0.077 \(\div\) 0.096). The obtained results clearly show that the differences are significant and can deepen the current knowledge about IBD. Neutrophils play a significant role in the immune response. Their importance in the development of IBD and their differences between UC and CD are not yet fully understood [13]. The role of neutrophils has been studied in various animal models of IBD for many years, but their participation in the pathogenesis of IBD remains poorly understood and no neutrophil-targeted molecules have been used and validated for the treatment of these pathologies \(OR\) = 0.96 (95% CI: 0.94 \(\div\) 1.11). Therefore, a better understanding of how to operate under these specific conditions is to provide new therapeutic pathways for IBD [35]. Creatinine is a metabolic product. Its level can be significantly changed in IBD. However, the level differences between UC and CD are not exactly known [12]. In this paper, we received a result indicating that its level is significantly different between IBD varieties.
