1. PICO Framework
Use PICO (Population, Intervention, Comparison, Outcome) to structure clinical queries:
P: diabetes mellitus, type 2[mh]
I: metformin[nm]
C: lifestyle modification[tiab]
O: glycemic control[tiab]
Query: diabetes mellitus, type 2[mh] AND (metformin[nm] OR lifestyle modification[tiab]) AND glycemic control[tiab]2. Iterative Refinement
Start broad, review results, refine:
1. diabetes → too broad
2. diabetes mellitus type 2 → better
3. diabetes mellitus, type 2[mh] AND metformin[nm] → more specific
4. diabetes mellitus, type 2[mh] AND metformin[nm] AND randomized controlled trial[pt] → focused3. Use Search History
Combine previous searches in Advanced Search:
#1: diabetes mellitus, type 2[mh]
#2: cardiovascular disease[mh]
#3: #1 AND #2 AND risk factors[tiab]4. Save Effective Searches
