As a data collection tool, the literature review involves activities such as identi- fying, recording, understanding, meaning-making, and transmitting information. Indeed, the literature review process is actualized through data collection.
In its opti- mal form, the literature review represents a formal data collection process wherein information is gathered in a comprehensive way. The CLR as a

In most cases, it is desirable to collect summary data separately for each intervention group of interest and to enter these into software in which effect estimates can be calculated, such as RevMan.
Sometimes the required data may be obtained only indirectly, and the relevant results may not be obvious.

Introduction#Section-5-1
Systematic reviews aim to identify all studies that are relevant to their research questions and to synthesize data about the design, risk of bias, and results of those studies.
Consequently, the findings of a systematic review depend critically on decisions relating to which data from these studies are presented and analysed.
Data collected for sy.

Managing and Sharing Data#Section-5-7
When data have been collected for each individual study, it is helpful to organize them into a comprehensive electronic format, such as a database or spreadsheet, before entering data into a meta-analysis or other synthesis.
When data are collated electronically, all or a subset of them can easily be exported for cleaning, consistency checks and an.

Sources of Data#Section-5-2
Studies are reported in a range of sources which are detailed later.
As discussed in Section 5.2.1, it is important to link together multiple reports of the same study.
The relative strengths and weaknesses of each type of source are discussed in Section 5.2.2.
For guidance on searching for and selecting reports of studies, refer to Chapter.

What data should be collected for systematic reviews?
Data collected for systematic reviews should be accurate, complete, and accessible for future updates of the review and for data sharing.
Methods used for these decisions must be transparent; they should be chosen to minimize biases and human error.

What is a systematic literature review (SLR)?
The study conducts a systematic literature review (SLR) with the objective to understand the feature, technology, method for data collection system in the previous research.
This understanding can be used as a base for developing a data collection system platform.

Why do review authors need a data collection form?
Review authors often have different backgrounds and level of systematic review experience.
Using a data collection form ensures some consistency in the process of data extraction, and is necessary for comparing data extracted in duplicate.
The completed data collection forms should be available to the CRG on request.
