A note on the estimation of confidence intervals for cost-effectiveness when costs and effects are censored [PDF]
, 2002 <i>Background</i>. The relation between methodological advances in estimation of confidence intervals (CIs) for incremental cost-effectiveness ratios (ICER) and estimation of cost effectiveness in the presence of censoring has not been ...

Outcome-dependent Sampling with Interval-censored Failure Time Data [PDF]
Biometrics, 2017 Summary Epidemiologic studies and disease prevention trials often seek to relate an exposure variable to a failure time that suffers from interval-censoring. When the failure rate is low and the time intervals are wide, a large cohort is often required so as to yield reliable precision on the exposure-failure-time relationship.

Arthritis Care &Research, EarlyView.Objective Lupus low disease activity state (LLDAS) is a validated treatment target in systemic lupus erythematosus (SLE), but limited studies have explored the role of LLDAS in lupus nephritis (LN). This study aims to investigate the frequency and predictors of LLDAS attainment and its benefit on LN relapse and renal function preservation in patients ...

Bayesian statistical inference of loglogistic model with interval-censored lifetime data [PDF]
, 2015 The properties of Palm Oil (PO) and Coconut Oil (CO) offer the potential for transformers Interval-censored data arise when a failure time say, T cannot be observed directly but can only be determined to lie in an interval obtained from a series of ...

Contact intervals, survival analysis of epidemic data, and estimation of R_0
, 2010 We argue that the time from the onset of infectiousness to infectious contact, which we call the contact interval, is a better basis for inference in epidemic data than the generation or serial interval.

Multiple imputation for threshold‐crossing data with interval censoring [PDF]
Statistics in Medicine, 1993 AbstractMedical statistics often involve measurements of the time when a variable crosses a threshold value. The time to threshold crossing may be the outcome variable in a survival analysis, or a time‐dependent covariate in the analysis of a subsequent event.

Hydroxychloroquine Associated With Lower Glomerular Filtration Rate Decline in Lupus Nephritis
Arthritis Care &Research, EarlyView.Objective Hydroxychloroquine (HCQ) protects kidney function in lupus nephritis (LN) by preventing flares, yet some cohort studies show no significant benefit in kidney function with HCQ. Clarifying these conflicting findings by showing early and long‐term benefits of HCQ on kidney function preservation is critical.

Multiple Imputation For Interval Censored Data With Auxiliary Variables [PDF]
, 2004 We propose a nonparametric multiple imputation scheme, NPMLE imputation, for the analysis of interval censored survival data. Features of the method are that it converts interval-censored data problems to complete data or right censored data problems to

Semiparametric Regression Analysis of Interval-Censored Competing Risks Data [PDF]
Biometrics, 2017 SummaryInterval-censored competing risks data arise when each study subject may experience an event or failure from one of several causes and the failure time is not observed directly but rather is known to lie in an interval between two examinations. We formulate the effects of possibly time-varying (external) covariates on the cumulative incidence or

Long‐Term Opioids in Gout: A Matched Cohort Study From the Veterans Health Administration
Arthritis Care &Research, EarlyView.Objective Though used frequently to treat flare, risk of long‐term opioid exposure in gout has not been well defined. In this study, we examined the hypothesis that people with gout are more likely than individuals without gout to be prescribed long‐term opioids over time.
