| EULAR Sjögren Syndrome Patient Reported Index (ESSPRI) | The ESSRPI is a patient-reported index for Sjogren's syndrome, which includes scores for sjogren's symptoms, limb pain, and physical fatigue. The weights of the three aspects are the same, and each aspect's score ranges from 0 to 10. ESSPRI is defined as the average of these three aspects, with a score range of 0 to 10. The higher the value, the more severe the condition. A symptom state of less than 5 is acceptable to the patient, while a symptom state of ≥5 is unsatisfactory to the patient. | week0、week4、week8、week12 |
| EULAR Sjögren syndrome disease activity index (ESSDAI) | Low activity is defined as ESSDAI < 5 points, moderate activity as 5≤ESSDAI≤13 points, and high activity as ESSDAI≥14 points | week0、week12 |
| Sjögren's Tool for Assessing Response (STAR) | It includes the assessment of ESSDAI system involvement, the subjective perception assessment of ESSPRI patients, the functional changes of salivary glands and lacrimal glands, and the evaluation of serological indicators for treatment response. A total score of ≥5 is considered a treatment response. | week12 |
| Composite of Relevant Endpoints for Sjogren Syndrome (CRESS) | It includes an assessment of five aspects，at least three out of the five have responded is defined as a response. | week 12 |
