Longitudinal Trend of Post-TNF Inhibitor Maintenance Treatment Lines: Mono vs. Combination Therapy. Each square matrix is vertically arranged in chronological order of maintenance therapy lines after tumor necrosis factor (TNF) inhibitor discontinuation and horizontally by individual maintenance therapy regimen, with color coding. Blue is methotrexate monotherapy; orange is methotrexate and tacrolimus combination therapy. The numbers of TNF inhibitor discontinuations per subsequent maintenance therapy regimen in the square matrices and those of subsequent relapses requiring resumption of biological disease-modifying antirheumatic drugs (bDMARD) or Janus kinase inhibitors (JAKi) in the black parallelograms are displayed
