  • Casual Reasoning with Survival Data 
    Ryalen, Pål Christie (Doctoral thesis / Doktoravhandling, 2019)
    The hazard rate is the most commonly studied parameter in survival analysis, but it is usually not suitable for causal inference. This thesis focuses on developing alternatives to hazards for analyzing survival data. ...
  • Causal inference in continuous time: an example on prostate cancer therapy 
    Ryalen, Pål Christie; Stensrud, Mats Julius; Fosså, Sophie Dorothea; Røysland, Kjetil (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
  • Causal inference with recurrent and competing events 
    Janvin, Matias; Young, Jessica G.; Ryalen, Pål Christie; Stensrud, Mats Julius (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Abstract Many research questions concern treatment effects on outcomes that can recur several times in the same individual. For example, medical researchers are interested in treatment effects on hospitalizations in heart ...
  • Long-Term Outcomes of Invasive vs Conservative Strategies for Older Patients With Non–ST-Segment Elevation Acute Coronary Syndromes 
    Berg, Erlend; Tegn, Nicolai Kloumann; Abdelnoor, Michael; Ryalen, Pål Christie; Røysland, Kjetil; Aaberge, Lars; Eek, Christian; Øie, Erik Harald; Juliebø, Vibeke; Gjertsen, Erik; Ranhoff, Anette Hylen; Gullestad, Lars; Nordstrand, Njord; Bendz, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Background Non–ST-segment elevation acute coronary syndrome (NSTE-ACS) is a frequent cause of hospital admission in older people, but clinical trials targeting this population are scarce. Objectives The After Eighty ...
  • Prognosis of cancer survivors: estimation based on differential equations 
    Ryalen, Pål Christie; Møller, Bjørn; Laache, Christoffer Haug; Stensrud, Mats Julius; Røysland, Kjetil (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Summary We present a method for estimating several prognosis parameters for cancer survivors. The method utilizes the fact that these parameters solve differential equations driven by cumulative hazards. By ...
  • Transforming cumulative hazard estimates 
    Ryalen, Pål Christie; Stensrud, Mats Julius; Røysland, Kjetil (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
