x402 APIFailing, checked 3 h ago

Gladman 2002 SLEDAI-2K: weighted sum of 24 caller-assigned descriptors present in the last 10 days (max 105). magent does not examine the patient. Proteinuria scores if >0.5 g/24 h (not original SLEDAI >3.5 g/24 h only). Rash, alopecia, and mucosal ulcers score if new or persistent (not new only). Not a diagnosis, not SLICC damage, not SELENA-SLEDAI flare rules, and not a medical device.
