Both studies make causality-related conclusions, but neither discusses what a feasible intervention to manipulate age at menarche in humans would look like in practice. I think without this discussion, the studies are not facilitating actions for future research, or clinical/policy decisions.

Observational study 1: Older age at menarche appears to reduce migraine risk. Further research is required to investigate the causality of this association.

Observational study 2: Our MR study suggested that later age at menarche was causally associated with a decreased risk of lung cancer.

Do you have any advice for PhD students on how to work with senior co-authors who insist that the language in observational studies should be strictly limited to associational? Assume that quitting the PhD or changing co-authors is not an option.

I’ve had the same impression while looking at academic epidemiology postdoc offers. So much focus on AI, machine learning, LLM experience. Are these the core skills we need now? What about subject matter knowledge, study design, bias, statistics, population health knowledge? Outdated?

The evaluation committee consists of one academic representative/usually a senior academic from each department of the faculty, the Pro Dean for Research Education, and a student representative.

Evaluated. The format is like a grant proposal and evaluation focuses on scientific rigor and project feasibility.

At UiT (Tromsø), we submit two protocols, one to the faculty and one to the ethics committee - even when using existing cohorts. Both must describe methods + variables you want to access (what & why). If changes are needed later, both protocols must be updated and re-approved.

Every time I pass this road, I think its so cool that the #TromsøStudy has its own directional traffic sign.🙂 #PopulationBasedStudy #Norway

Excited for my first #SER2025 in Boston next week! Looking forward to meeting US collaborators in person who are advising me on how to properly use target trial emulation and G-methods in #alcohol and #cancer observational studies.

Is smoking a confounder or a mediator in alcohol-related mortality in observational studies? We share some thoughts in our new preprint: papers.ssrn.com/sol3/papers....

New non-profit journal on #publichealth #openaccess open #peerreview with reviewers getting paid for their work.

Highly recommended! Also, very helpful to improve the quality of my own manuscripts.
