Excluding any missing values. Significant values (p < 0.05) are highlighted in bold

^aDifferences between two groups were evaluated by t-test, and between three or more groups by one-way analysis of variance

^bDifferences in mean values were assessed using Tukey’s multiple comparison test

^cA single diagnosis included multiple diagnoses within the same disease group; multiple diagnoses included any outside the disease group of rheumatic disease and allergies
