Keywords such as delivery, health care, and government, with 891, 1,542, and 183 occurrences, respectively, form the most central keywords.
The lack of central cross-cutting keywords or clusters connotes a distinct lack of integration between health from an epidemiological perspective (red and green clusters) versus health systems thinking in the 1990s.
For example, keywords most central to Figure 3 (i.e., the red cluster) and intensely cited in the literature concern services for primary health care patients, organizational issues related to provider-client relationships, - access to care, -, - the quality of services,,,, and the management of frontline workers.
We conducted updated electronic searches for trials in Medline, Embase, and Central using the following keywords, and a modified version of the Cochrane highly sensitive search strategy: FSH, follicle-stimulating hormone, recombinant, hMG, and human menopausal gonadotropin/gonadotropin. Trials including women undergoing transfer from donor oocytes or embryos were excluded.
They performed a literature search using electronic bibliographic databases (Medline, EMBASE, PubMed Central) from 1970 to 2006 with the keywords: complex regional pain syndrome, reflex sympathetic dystrophy, neuropathic pain, and causalgia.
This model was established around the "Descriptor" which is the central concept of the terminologies (aka "keyword").
We used [smoking AND (tooth loss OR tooth extraction)] for additional searches of EMBASE (limited to title) and CENTRAL (limited to title, abstract or keywords).
The central dashboard for brands features message archiving, keyword flagging and filtering, workflow and approval capabilities.
step 2) MEDLINE, EMBASE, and CENTRAL databases were searched using the exploded keyword "head injuries:ME" or "head injuries:TI".
Sixty-three respondents made 68 comments, many of which used terms such as "crucial" and "essential" to describe the role of the central support system in sustaining their efforts (keyword analysis, Figure 4 and Supplemental Material S4).
