The goal of this retrospective, observational study is to learn more about the risks and benefits of methotrexate lab monitoring. The main question it aims to answer is: \- Is reduced methotrexate lab monitoring non-inferiorly safe when compared to standard lab monitoring? Differences in end-organ damage and/or death will be compared between participants who have previously been treated with methotrexate for various rheumatic diseases and have undergone varying intervals of methotrexate lab monitoring
