We compared the correlation between IL-2, IL-4, IL-5 and IL-12p70 respectively with baseline clinical variables including age, disease course, MG activities of daily living (MG-ADL) score, MGFA-quantitative MG test (MGFA-QMG), MG quality of life 15-item (QoL-15) questionnaire, and MG manual muscle test (MMT). Here, IL5 is linked to myasthenia gravis.
