TL;DR: A Bayesian framework for integrating the two types of test data for better reliability estimates is presented, which allows the reliability to depend on covariates such as age.
Abstract: A system with several components may undergo full system pass/fail testing as well as quality assurance testing at the single component level. The component tests are informative about system reliability, although they measure different things than the full system tests. We present a Bayesian framework for integrating the two types of test data for better reliability estimates. Our formulation allows the reliability to depend on covariates such as age. One result of the inference is a better understanding of the relationship between component tests and system performance. We illustrate the ideas using a small subsystem of a larger (proprietary) system.

TL;DR: The technique of manually assessing anterior humeral head translation studied has poor overall interrater reliability and only fair intrarater reliability, while the test-retest accuracy of humeralHead translation is enhanced when examiners only determine the relationship of the humeral heads relative to the glenoid rim.

TL;DR: The SRI-50 is reliable to assess ≥ 50% improvement in lupus disease activity and performs equally well in trained as well as untrained rheumatologists.
Abstract: Objective. To test the interrater and intrarater reliability of the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) Responder Index (SRI-50), an index designed to measure ≥ 50% improvement in disease activity between visits in patients with systemic lupus erythematosus. Methods. This was a multicenter, cross-sectional study with raters from Canada, the United Kingdom, and Argentina. Patient profile scenarios were derived from real adult patients. Ten rheumatologists from university and community hospitals and postdoctoral rheumatology fellows participated. An SRI-50 data retrieval form was used. Each rheumatologist scored SLEDAI-2K at the baseline visit and SRI-50 on followup visit, for the same patients, on 2 occasions 2 weeks apart. Physician global assessment (PGA) was determined on a numerical scale at baseline visit and a Likert scale on followup visit. Interrater and intrarater reliability was assessed using intraclass correlation coefficient (ICC) and kappa statistics whenever applicable. Results. Forty patient profiles were created. The ICC performed on 80 patient profiles for interrater ranged from 1.00 for SLEDAI-2K and SRI-50 to 0.96 for PGA. The intrarater ICC for SLEDAI-2K, SRI-50, and PGA scores ranged from 1.00 to 0.86. Substantial agreement was determined for the interrater Likert scale, with a kappa statistic of 0.57. Conclusion. The SRI-50 is reliable to assess ≥ 50% improvement in lupus disease activity. Use of the SRI-50 data retrieval form is essential to ensure optimal performance of the SRI-50. SRI-50 can be used by both rheumatologists and trainees and performs equally well in trained as well as untrained rheumatologists.
