Everything you learn in medicine (and life) needs to be critically appraised. This can be mentally exhausting but is essential as you develop your own understanding of the evidence (and dogma) on which current medical practice is based. Below are a series of links to resources you may find useful in critically appraising papers. Back in the bad old days aspiring consultants used to have to complete a Clinical Topic Review on a subject of their choice, nowadays you have a management portfolio. Lots of these links are a little older and reference CTR but don’t be put off, the critical thinking behind them is still as relevant today.
