Built-in selection or confounder bias? Dynamic Landmarking in matched propensity score analyses.

BMC Med Res Methodol

December 2024

German Diabetes Center, Leibniz Center for Diabetes Research, Institute for Biometrics and Epidemiology, Heinrich-Heine-University Düsseldorf, Düsseldorf, Germany.

Background: Propensity score matching has become a popular method for estimating causal treatment effects in non-randomized studies. However, for time-to-event outcomes, the estimation of hazard ratios based on propensity scores can be challenging if omitted or unobserved covariates are present. Not accounting for such covariates could lead to treatment estimates, differing from the estimate of interest.

Aims: Two prerequisites must be met for the precision treatment approach to be beneficial for treated individuals. First, there must be treatment heterogeneity; second, in case of treatment heterogeneity, clinical predictors to identify people who would benefit from one treatment more than from others must be available. There is an established meta-regression approach to assess these two prerequisites that relies on measuring the variability of a clinical outcome after treatment in placebo-controlled randomised trials.

Article Synopsis
  • Event-driven trials maintain the target power for treatment effects by focusing on obtaining a required number of events, but they may take longer if the actual event rate is lower than expected.* -
  • Blinded sample size reestimation (BSSR) uses interim data to adjust sample sizes if initial assumptions are incorrect, aiming to achieve the necessary number of events within the planned timeline.* -
  • A new flexible spline-based BSSR method, specifically the Royston-Parmar model, shows improved accuracy in predicting event counts compared to traditional parametric models, as evidenced by simulation studies and real trial applications.*

Electronic address:

Background: High-intensity interval training (HIIT) has been shown to improve cardiorespiratory fitness (V˙O max) but may ameliorate insulin sensitivity only in insulin-resistant humans. It is yet unclear whether these benefits persist after detraining and to which extent duration and effectiveness of metabolic improvements differ between individuals without and with prediabetes or type 2 diabetes (T2D). Understanding these differences is relevant for developing targeted exercise training modes for individuals with different stages of dysglycemia.

Article Synopsis
  • The study examined the relationship between Time in Range (TIR) and Time in Tight Range (TTR) with HbA1c levels in youth and young adults with type 1 diabetes using data from a large diabetes registry.
  • Results showed a strong correlation between TIR and TTR (r = 0.965) and between both metrics and HbA1c levels, indicating that higher TIR and TTR are associated with lower HbA1c levels.
  • Moreover, regression analysis suggested that TIR might be a slightly better predictor of HbA1c compared to TTR, especially in individuals with high blood glucose variability.

Modeling Chronic Disease Mortality by Methods From Accelerated Life Testing.

Stat Med

December 2024

German Diabetes Center, Leibniz Institute for Diabetes Research at Heinrich-Heine-University Düsseldorf, Institute for Biometrics and Epidemiology, Düsseldorf, Germany.

We propose a parametric model for describing chronic disease mortality from cohort data and illustrate its use for Type 2 diabetes. The model uses ideas from accelerated life testing in reliability theory and conceptualizes the occurrence of a chronic disease as putting the observational unit to an enhanced stress level, which is supposed to shorten its lifetime. It further addresses the issue of semi-competing risk, that is, the asymmetry of death and diagnosis of disease, where the disease can be diagnosed before death, but not after.
