• Define: Use few essential words that are easily recognized by readers, and accurately describe your findings.
• Attract: Your paper title is the first, and maybe only, part of your paper to be read.
• Use common MeSH terminology: Readers of search, indexing and abstracting services depend on the accuracy and recognition of your title. Wrong words lead to wrong readers.
