A Biostatistician’s Guide to Navigating Online Health Information Like a Scientist

The article encourages people to treat personal health research like a scientific inquiry, beginning with a clear question that specifies the intervention, desired result, target group and timing. It advises using PubMed to locate systematic reviews, ensuring the study’s exposure, outcome, population and period align with the question, and interpreting the review’s certainty rating. If a suitable review is unavailable or low-certainty, the next step is to find well-designed randomized controlled trials that match the asker’s characteristics.

In the absence of trials, observational studies or animal experiments can provide clues, though their limitations are highlighted. The author also warns against over-reliance on personal anecdotes and stresses checking funding sources and conflicts of interest. Finally, the piece recommends cross-checking multiple reputable sources and consulting healthcare professionals to turn evidence into informed decisions.
