From: Urinary TWEAK as a biomarker of lupus nephritis: a multicenter cohort study
Urinary TWEAK levels at different timepoints relative to a lupus nephritis flare. Urinary TNF-like weak inducer of apoptosis (uTWEAK) levels of 13 lupus nephritis (LN) patients followed in the Ohio SLE Study cohort, taken 6, 4 and 2 months before and after a LN flare, including at the time of the flare itself (timepoint 0). Graph represents least-squares (LS) means with standard error. *P < 0.05 compared with uTWEAK level at flare.
