Collect 50 scientific papers of a specific kind

I would like to get a set of 50 (or more) scientific papers from medical journals that fit the following criteria: * **some kind of formal decision model must be tested or derived from data in the paper** (for instance, the enclosed paper shows such a formal decision model on page 1502). This is typically something that looks like a decision tree or sometimes a prediction equation. * published after 1990, the more recent, the better * delivered in pdf * The papers should consider different decision models, I do not want more than one paper about a single model. Review studies about this topic can also be included and count too Process: When you have found ten papers, send them to me, and I will give you feedback as to whether you are on the right track. Note: If you find that you can easily find more papers, we can negotiate about a larger batch. After you deliver the papers, I will go through them to check if they fit the criteria. When in doubt along the way, ask! You need: - library access (I cannot give that to you), for instance through PubMed - enough download capacity (to download the files) Possible search terms you might want to use in a database such as PubMed: - decision model - decision tree - computer-based clinical decision - (medical) decision aids - ?
