A ManyModels project would be a valuable contribution. Almost all published literature using LLMs is out of date by time of peer-review; maybe a living report to show 'current' state of LLMs? What's the experimental design?

this may end up becoming how evidence synthesis is done in the future (with teams of AI agents collaborating on each step of the process and continuously updating reviews/meta-analyses when new evidence becomes available)

Challenging indeed! Regression based models will only get us so far. I think formal models (eg ordinary differential equations) are needed at the idiographic level. I'm hopeful that personal AI agents will be developed to do this type of continual data collection and modeling in the future.

Functional dependence can be best prospectively estimated by age, psychological distress, physical fitness, physical activity, chronic conditions, and sex. These predictors can estimate functional dependence more than 6 years in advance with high accuracy. www.medrxiv.org/content/10.1...

The beneficial effect of prestroke physical activity on activities of daily living (ADL) limitations after stroke is stronger than its effect in matched adults without stroke followed for a similar number of years. @matthieuboisgontier.com academic.oup.com/ptj/article/...
