Literature search for research planning and identification of research problem

Abstract: Literature search is a key step in performing good authentic research. It helps in formulating a research question and planning the study. The available published data are enormous; therefore, choosing the appropriate articles relevant to your study in question is an art. It can be time-consuming, tiring and can lead to disinterest or even abandonment of search in between if not carried out in a step-wise manner. Various databases are available for performing literature search. This article primarily stresses … Show more

“…The keyword ‘ Cannabis sativa ’ was used with the Boolean operators AND ‘hemp’ and NOT ‘marijuana’. Using ‘AND’ fetched articles that mention both the words, while using ‘NOT’ fetched articles containing the first word, but not the second, thus narrowing the search (Grewal et al ., ). No time, language or document type restrictions were applied.…”

“…The PICO in this study was set as follows: Population (P), tuberculosis patient; Intervention (I), GSTM1 or GSTT1 polymorphisms; Comparator (C), gene deletion and wild type; and Outcomes (O), liver injury or hepatotoxicity. The search strategies were constructed by combining search terms using Boolean operators, including 'OR' within the same domain and 'AND' amongst domains (28).…”

“…Various tools have been developed to mine and retrieve data from biomedical literature in relation to the expression levels of certain biomarkers within specific diseases and how they interact to modify the function of various pathways (11). Due to the immense volume of biomedical literature available on NCBI, MeSH terms were introduced to improve the literature search and retrieval process (12). These allow for the retrieval of documents that possess similar content but use various synonyms, abbreviations or wording regarding the same biological term e.g.…”

“…These allow for the retrieval of documents that possess similar content but use various synonyms, abbreviations or wording regarding the same biological term e.g. 'preeclampsia' or 'pre-eclampsia,' allowing for the construction of a refined and specific literature search (12). Reactome, a data analysis tool, which contains 10719 human genes interacting into 2102 pathways, was designed to aid in the discovery of biological interactions and reactions occurring under normal physiological and disease conditions (13).…”
