MeSH search strategy

Stage 1 Diseases Stage 2 Drugs Stage 3 Study methods
1exp glaucoma or exp glaucoma, open angle 4exp prostaglandins F, synthetic 7exp clinical trials or exp randomised controlled trials
2exp ocular hypertension 5exp adrenergic β antagonists 8exp double blind method
31 or 264 and 59exp single blind method
10exp random allocation
117 or 8 or 9 or 10
Finally, we combined three stages together using: 3 and 6 and 11
  • exp = explode.
