Z‐residuals diagnostics for Cox models: Functional‐form misspecification versus nonproportional hazards

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Primary biliary cholangitis (PBC) is a progressive autoimmune cholestatic disease for which modelling death, with transplantation as a competing event, is clinically important. Cox proportional hazards (PH) models are widely used, but standard diagnostics detect lack of fit without distinguishing non‐PH from misspecified covariate functions ...

Model Misspecification, Learning and Real Exchange Rate Dynamics

open access: yes, 2015
Based on Lewis & Markiewicz (2009), the purpose of this paper is to explore if implied real exchange rate dynamics are similar to these obtained from observed data under a model with misspecification.

Population Pharmacokinetics and Exposure‐Response Analyses to Support Cofetuzumab Pelidotin (ABBV‐647) Dose Optimization in Non‐Small Cell Lung Cancer Patients

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Cofetuzumab pelidotin (Cofe‐P) is an anti‐protein tyrosine kinase 7 (PTK7) antibody‐drug conjugate (ADC) being investigated for the treatment of adults with PTK7‐expressing, recurrent non‐small cell lung cancer (NSCLC). The first‐in‐human (FIH) trial demonstrated tolerability of dosages ≤ 2.8 mg/kg once every 3 weeks (Q3W) and ≤ 3.2 mg/kg Q2W ...

Tramadol Co‐Administration with Oxycodone or Hydrocodone Increases Opioid Burden without Improving Postoperative Pain Control

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Tramadol is frequently co‐prescribed with oxycodone or hydrocodone after surgery under the assumption that its dual mechanism of action provides an opioid‐sparing benefit. However, evidence supporting this practice is limited and inconsistent. We conducted a secondary analysis of the multicenter IGNITE ADOPT‐PGx pragmatic trial of patients undergoing ...

Pharmacokinetics of Rifapentine and Desacetyl Rifapentine in Maternal Plasma and Breast Milk & Infant Cord Blood and Plasma: A Model‐Based Analysis of Mother–Infant Pairs for Tuberculosis Prevention

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
IMPAACT 2001 (NCT02651259) evaluated the safety and pharmacokinetics (PK) of once‐weekly isoniazid and rifapentine in pregnant and postpartum women for tuberculosis prevention. Rifapentine (RPT) and desacetyl rifapentine (desRPT) PK data were collected in maternal plasma, breast milk, infant cord blood, and infant plasma.

A partially heterogeneous weighted fusion learning method for potential heterogeneous treatment effect in multi-site survival study

open access: yesBMC Medical Research Methodology
Background In multi-site studies in clinical practice, the treatment effects may exhibit potential heterogeneity across different sites. Additionally, propensity score methods used to adjust for confounding may suffer from model misspecification, which ...

Considerations for the Integration of Clinical Trials and Real‐World Data

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
As clinical decision‐making increasingly moves toward individualized and context‐specific treatment recommendations, reliance on any single evidence source, randomized or observational, may be insufficient. Principled integration of randomized controlled trials and real‐world data, grounded in explicit causal frameworks, offers a path toward evidence ...

Orchestrating Green Transformation: How AI Adoption Enables Corporate Carbon Neutrality

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As carbon neutrality has become a central goal of global climate governance, how firms achieve low‐carbon transformation has emerged as a critical research issue. However, prior studies have primarily focused on macro‐ or industry‐level analyses, offering limited and fragmented insights into how digital technologies—particularly AI—affect firm‐

New Misspecification Tests for Multinomial Logit Models [PDF]

open access: yes, 2019
Misspecification tests for Multinomial Logit [MNL] models are known to have low power or large size distortion. We propose two new misspecification tests.
