Fraser 2006.
| Methods |
Method of identification of reference standards: articles included in the development systematic reviews Method of deriving methodological filter terms: analysis of reference standard: the terms related to study design from reference standard were assessed and identified as candidate terms for the MEDLINE and Embase methodology filters. The candidate terms were tested in reverse order of precision or specificity to see if removal affected sensitivity and re‐instated if they did. Therefore, the reference standard consisted of the term with highest precision and specificity while sensitivity was maximised. |
|
| Data |
Reference standard year: development set 2000‐2004; validation set 2000‐2004 and 1990‐2004 Number of reference standards: 217 articles for combined MEDLINE/Embase in development systematic reviews Number of validation standard records: 39 and 30 for combined MEDLINE/Embase in validation systematic reviews, PRK and tonsillectomy, respectively |
|
| Comparisons |
Reference standard also contained non‐gold standard records: yes. There was no gold standard Description of non‐gold standard records if used in reference standard: reference standard, which used articles retrieved by electronic search in the included development systematic reviews |
|
| Outcomes |
Performance of filters: sensitivity and precision Number of methodological filters developed: 6: Precision Terms Filters and Specificity Terms Filters for MEDLINE, for Embase, and for combined MEDLINE/Embase, respectively |
