ALB and neuropathy: As shown in Supplementary Table 5, among the 12 variables in the model, the bias regression coefficients for the seven variables of neuropathy (NP) in diagnostic basis, fever>38°C, SLEDAI at discharge, cardiopulmonary-involvement, abnormal alanine aminotransferase (ALB), abnormal blood urea nitrogen (BUN), and abnormal Anti-ds-DNA were all greater than 0, while the risk coefficients were greater than 1, with significant differences between groups (p<0.05).
