A Novel Fractional Forecasting Model for Time Dependent Real World Cases

Revstat Statistical Journal
The grey modelling in the prediction of time series has been one of the interesting study fields recently due to its efficiency and convenience. Fractional grey models, on the other hand, have become preferable, despite the difficulty in calculations ...

Combination Therapy in Participants With Active Psoriatic Arthritis Using Subcutaneous Guselkumab and Golimumab: Week 24 Results From a Phase 2a, Multicenter, Randomized, Double‐Blind, Proof‐of‐Concept Study

Arthritis &Rheumatology, EarlyView.
Objective To assess guselkumab + golimumab combination therapy versus guselkumab monotherapy in participants with active psoriatic arthritis (PsA) and inadequate response to tumor necrosis factor inhibitors (TNFi‐IR). Methods Adults with active TNFi‐IR PsA (three or more tender/swollen joints) were randomized (2:1) to subcutaneous guselkumab (100 mg) +

Semiparametric optimal estimation with nonignorable nonresponse data

, 2021
When the response mechanism is believed to be not missing at random (NMAR), a valid analysis requires stronger assumptions on the response mechanism than standard statistical methods would otherwise require.

Determinants of Difficult‐to‐Manage and Treatment‐Refractory Axial Spondyloarthritis: A Cross‐Sectional Analysis Within a Longitudinal Cohort

Arthritis &Rheumatology, EarlyView.
Objective The purpose of this study was to estimate the prevalence of difficult‐to‐manage (D2M) and treatment‐refractory (TR) axial spondyloarthritis (axSpA) and to identify factors associated with D2M and TR disease in a longitudinal cohort. Methods We performed a cross‐sectional analysis on data from the Schroeder Arthritis Institute Spondylitis ...

Angiotensinogen promoter methylation predicts bevacizumab treatment response of patients with recurrent glioblastoma

Molecular Oncology, 2020
Patients with recurrent glioblastoma achieving response to bevacizumab combined with chemotherapy have clinical improvement and prolonged survival. High gene expression of angiotensinogen (AGT) is associated with a poor bevacizumab response.

The dilemma of survey nonresponse

Library & Information Science Research, 2003
An examination of the library and information science (LIS) literature reveals that surveys published from 1996 through 2001 in three major LIS journals have an average response rate of 63%, and almost three fourths of the surveys have a response rate less than 75% (the level that is widely held to be required for generalizability). Consistent with the

The American College of Rheumatology Updated Recommended Methods for Development of Disease Classification and Response Criteria

Arthritis &Rheumatology, EarlyView.
Disease classification criteria and response criteria are important tools in the conduct of observational studies and clinical trials for rheumatic diseases. This paper updates methodologic guidance for classification and response criteria funded, developed and/or endorsed by the American College of Rheumatology (ACR), incorporating contemporary ...
