Antiviral Therapy, 2013
Background There is a high incidence of tuberculosis (TB) early after antiretroviral therapy (ART) initiation. This historical cohort study evaluated the association of efavirenz (EFV) compared to nevirapine (NVP) with post-ART TB among patients initiated on first-line ART from 2005 to 2009 in a large, urban HIV clinic in Uganda. Methods Hazard ratios (

Opioid use disorder (OUD) is a chronic condition that affects three million people in the United States and 16 million people worldwide. Randomized controlled trials (RCTs) are the gold standard for OUD, but there are multiple methodological complexities present in the analysis of randomized controlled OUD trials.

Pharmacoepidemiology and Drug Safety, 2012
ABSTRACTPurposeWhen medications are modified in response to changing clinical conditions, confounding by indication arises that cannot be controlled using traditional adjustment. Inverse probability of treatment weights (IPTWs) can address this confounding given assumptions of no unmeasured confounders and that all patients have a positive probability ...

Pharmaceutical Statistics, 2009
AbstractIn survival analysis, treatment effects are commonly evaluated based on survival curves and hazard ratios as causal treatment effects. In observational studies, these estimates may be biased due to confounding factors. The inverse probability of treatment weighted (IPTW) method based on the propensity score is one of the approaches utilized to ...

This study aims to evaluate outcomes in patients with mesenteric artery embolism (MAE) who received primary endovascular therapy (EVT) or laparotomy, and investigate risk factors for 30-day mortality.A retrospective analysis of 94 MAE patients who underwent two different treatment strategies was undertaken. An inverse probability of treatment weighting

Research on Stock Market Prediction based on Inverse Probability of Treatment Weighting Method
Science and Technology of Engineering, Chemistry and Environmental ProtectionAlthough randomized controlled trials (RCTs) are considered the best method to evaluate the impact of interventions, their application in the financial industry is not feasible due to ethical and practical issues. Propensity Score Matching (PSM) minimizes the problem of bias in observational studies.
