The CATmaker software, developed by Douglas Badenoch from the Centre for Evidence-Based Medicine, is a tool which helps you create Critically Appraised Topics, or CATs, for the key articles you encounter about therapy, diagnosis, prognosis, aetiology/harm and systematic reviews of therapy.

It carries out the following functions:

• prompts you for your clinical question, your search strategy and key information about the study you found;
• provides on-line critical appraisal guides for assessing the validity and usefulness of the study;
• automates the calculation of clinically useful measures (and their 95% confidence intervals);
• helps you formulate clinical "Bottom Lines" from what you've read;
• creates 1-page summaries (CATs) that are easy to store, print, retrieve, and share (as both text and HTML files);
• helps you remember when to update each CAT you create;
• helps you to teach others how to practice EBM;
• and most importantly, it looks really cool.
