CD33 and systemic lupus erythematosus: The CD14+ dataset produced one module with significantly positive correlation to SLE (yellow: n = 362, r = 0.837, p = 4.22e-6) and one module with significantly negative correlation to SLE (sienna3: n = 229, r = -0.852, p = 1.84e-6), and the CD33+ dataset produced two modules significantly positively correlated to SLE (violet: n = 182, r = 0.718, p = 7.88e-4; sienna3: n = 133, r = 0.784, p = 1.17e-4) and one module significantly negatively correlated to SLE (darkolivegreen: n = 227, r = -0.549, p = 0.0182) (Fig 2B).
