Pragmatic Clinical Trials in the Rubric of Structural Causal Models

no code implementations28 Apr 2022 Riddhiman Adib, Sheikh Iqbal Ahamed, Mohammad Adibuzzaman

Explanatory studies, such as randomized controlled trials, are targeted to extract the true causal effect of interventions on outcomes and are by design adjusted for covariates through randomization.

CKH: Causal Knowledge Hierarchy for Estimating Structural Causal Models from Data and Priors

no code implementations28 Apr 2022 Riddhiman Adib, Md Mobasshir Arshed Naved, Chih-Hao Fang, Md Osman Gani, Ananth Grama, Paul Griffin, Sheikh Iqbal Ahamed, Mohammad Adibuzzaman

Using CKH, we present a methodological framework for encoding causal priors from various information sources and combining them to derive an SCM.

Causal Discovery on the Effect of Antipsychotic Drugs on Delirium Patients in the ICU using Large EHR Dataset

no code implementations28 Apr 2022 Riddhiman Adib, Md Osman Gani, Sheikh Iqbal Ahamed, Mohammad Adibuzzaman

To explore safety outcomes associated with APD, we aim to build a causal model for delirium in the ICU using large observational data sets connecting various covariates correlated with delirium.

Structural Causal Model with Expert Augmented Knowledge to Estimate the Effect of Oxygen Therapy on Mortality in the ICU

no code implementations28 Oct 2020 Md Osman Gani, Shravan Kethireddy, Marvi Bikak, Paul Griffin, Mohammad Adibuzzaman

Recent advances in causal inference techniques, more specifically, in the theory of structural causal models, provide the framework for identification of causal effects from observational data in the cases where the causal graph is identifiable, i. e., the data generating mechanism can be recovered from the joint distribution.

Identifying and Analyzing Sepsis States: A Retrospective Study on Patients with Sepsis in ICUs

1 code implementation21 Sep 2020 Chih-Hao Fang, Vikram Ravindra, Salma Akhter, Mohammad Adibuzzaman, Paul Griffin, Shankar Subramaniam, Ananth Grama

Sepsis accounts for more than 50% of hospital deaths, and the associated cost ranks the highest among hospital admissions in the US.
