- Nuclo?ide = nucleoside or nucleotide
- Physician NEAR relationship retrieves records that contain the words in the same field E.g. both words in the Title; in the abstract, and so on physician adj5 relationship retrieves records that contain the words physician and relationship within five words of each other in either direction . E.g. physician patient relationship , patient physician relationship , relationship of the physician to the patient , and so on.

- The OR operator lets you retrieve records that contain any of your search terms. For example, the search heart attack or myocardial infarction retrieves records that contain heart attack, myocardial infarction or both terms. Results are all inclusive The AND operator lets you retrieve only those records that include all of your search terms. For example, the search blood pressure and stroke retrieves only those records that contain both terms blood pressure and stroke together in the same record. Results exclude records that do not contain both terms.
- The NOT operator lets you retrieve records that contain your first term but exclude the second term. In this way, you can restrict the scope of your results. For example, the search health reform not health maintenance organizations retrieves only those records that contain the term health reform but exclude the term health maintenance organizations. http://www.ovid.com.vdicp.health.fgov.be:8080/site/help/documentation/ospb/en/syntax.htm#operators 1 deoxyglucose.ti.ab.rw.sh 2 deoxy-glucose.ti.ab.rw.sh 3 fluorodeoxyglucose.ti.ab.rw.sh 4 18fluorodeoxyglucose.ti.ab.rw.sh 5 fluodeoxyglucose.ti.ab.rw.sh 6 fdg$.ti.ab.rw.sh 7 18fdg.ti.ab.rw.sh 8 f-18-dg.ti.ab.rw.sh 9 fluoro-2-deoxy-d-glucose.ti.ab.rw.sh 10 2fluoro-2deoxyglucose.ti.ab.rw.sh 11 fluoro-d-glucose.ti.ab.rw.sh 12 or/1-11
- Nuclo?ide = nucleoside or nucleotide
- Filtered resources appraise the quality of studies and often make recommendations for practice Unfiltered resources: Evidence is not always available via filtered resources. Searching the primary literature may be required. It is possible to use specific search strategies in MEDLINE and other databases to retrieve the best available evidence.
