The association between vitamin K and medial tibial-femoral knee osteoarthritis progression: Data from the osteoarthritis initiative.

Objective: We sought to examine the prospective association of vitamin K with radiographic progression of knee osteoarthritis.

Methods: In OAI, 1977 participants with radiographic knee OA and having dietary data at baseline were followed up to 12, 24, 36 and 48 months. Vitamin K was assessed with a Block Brief Food Frequency Questionnaire completed at baseline.

Remnant cholesterol is prospectively associated with cardiovascular disease events and all-cause mortality in kidney transplant recipients: the FAVORIT study.

Background: The cholesterol content of circulating triglyceride-rich lipoproteins is characterized as remnant cholesterol, although little is known about its role in the development of cardiovascular disease (CVD) outcomes, all-cause mortality or transplant failure in kidney transplant recipients (KTRs). Our primary aim was to investigate the prospective association of remnant cholesterol and the risk of CVD events in renal transplant recipients with secondary aims evaluating remnant cholesterol and renal graft failure and all-cause mortality among participants in the Folic Acid for Vascular Outcome Reduction in Transplantation (FAVORIT) trial.

Methods: Among 4110 enrolled participants, 98 were excluded for missing baseline remnant cholesterol levels and covariates.
