Generating inverse probability weights for both binary and continuous treatments

, 2020
My program evaluation class is basically a fun wrapper around topics in causal inference and econometrics. I'm a big fan of Judea Pearl-style "causal revolution" causal graphs (or DAGs), and they've made it easier for both me and my students to understand econometric approaches like diff-in-diff, regression discontinuity, and instrumental variables.

Augmented inverse probability weighted estimation for conditional treatment effect

Journal of Nonparametric Statistics
The Augmented Inverse Probability Weighted (AIPW) estimation has been extensively studied in various scenarios across diverse research areas. This investigation explores the asymptotic properties of the AIPW estimator for the conditional average treatment effect.

Non-collapsibility and built-in selection bias of period-specific and conventional hazard ratio in randomized controlled trials

BMC Medical Research Methodology
Background The hazard ratio of the Cox proportional hazards model is widely used in randomized controlled trials to assess treatment effects. However, two properties of the hazard ratio including the non-collapsibility and built-in selection bias need to

Influence of moderate left subclavian artery stenosis on outcomes after coronary bypass surgery in patients requiring hemodialysisCentral MessagePerspective

JTCVS Open
Objectives: Left subclavian artery stenosis in patients requiring hemodialysis can cause coronary steal syndrome via the left internal thoracic artery (LITA) graft to the left anterior descending artery (LAD), potentially leading to graft failure.

Statin Treatment and Clinical Outcomes of Heart Failure Among Africans: An Inverse Probability Treatment Weighted Analysis

Journal of the American Heart Association, 2017
Background Randomized control trials of statins have not demonstrated significant benefits in outcomes of heart failure ( HF ). However, randomized control trials may not always be generalizable. The aim was to determine whether statin and statin type–lipophilic or –hydrophilic improve

On variance estimation of the inverse probability‐of‐treatment weighting estimator: A tutorial for different types of propensity score weights

Statistics in Medicine
Propensity score methods, such as inverse probability‐of‐treatment weighting (IPTW), have been increasingly used for covariate balancing in both observational studies and randomized trials, allowing the control of both systematic and chance imbalances. Approaches using IPTW are based on two steps: (i) estimation of the individual propensity scores (PS),

Nonprescription Magnesium Supplement Use and Risk of Heart Failure in Patients With Diabetes: A Target Trial Emulation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Both diabetes and low magnesium‐containing food intake may increase the risk of heart failure (HF). However, the effect of nonprescription magnesium supplements on the risk of HF or major adverse cardiac events in patients with diabetes is ...

Local ablation vs partial nephrectomy in T1N0M0 renal cell carcinoma: An inverse probability of treatment weighting analysis

Cancer Medicine, 2020
Objective To compare the survival outcomes of local ablation (LA) and partial nephrectomy (PN) for T1N0M0 renal cell carcinoma (RCC). Method We identified 38,155 T1N0M0 RCC patients treated with PN or LA in 2004‐2016 from the retrospective Surveillance ...

Use and reporting of inverse-probability-of-treatment weighting for multicategory treatments in medical research: a systematic review

Journal of Clinical Epidemiology
Causal inference methods for observational data represent an alternative to randomised controlled trials when they are not feasible or when real-world evidence is sought. Inverse-probability-of-treatment weighting (IPTW) is one of the most popular approaches to account for confounding in observational studies.

Association between dietary inflammatory index and hyperglycemia among adults in China: an analysis of the CHNS database

Zhongguo gonggong weisheng
ObjectiveTo investigate the associations of the energy-adjusted dietary inflammatory index (E-DII) with hyperglycemia risk and fasting plasma glucose (FPG) level among adults in China. MethodsA total of 9 363 adults aged ≥ 18 years who participated in at
