The question behind the headline
People with osteoarthritis; varied formulations, comparators and pain scales.

Three questions to take forward
- Was the study population similar to the person or situation I have in mind?
- Did it measure an outcome people feel or experience, or only a laboratory marker?
- How do formulation, usual care, absolute benefit and adverse effects change the interpretation?
