Methodology One of the basic principles that is used to combine valuable scientific findings and knowledge from often interdisciplinary domains is called systems analysis. Causal loop diagrams (CLDs) functioned as a tool to illustrate the principle of causality of 25(OH)D serum levels on the human metabolism and form the basis for systems analysis (Mabin et al., 2006). Such causal loop diagrams are powerful instruments for problem identification and problem resolving purposes by breaking down a comprehensive system into fragments in order to enhance its comprehensibility (Haraldsson, 2004).
Visualizing concepts makes it much easier to understand complex correlations and casualties (i.e. Cause and effect mechanisms). The problem (in this case immune systems that have difficulties coping with COVID-19) stands in the center of the systems analysis.
Data on the impact of vitamin D 3 on the immune system have been collected and elaborated in the results and discussion section. This publication illustrated the metabolic mechanisms behind that observed phenomenon. Ethics approval and consent to participate Not applicable.
