BDT and MV participated in the data collection and references search.
Additional details on data collection and references are provided in Supplemental Material, "Additional information about data collection".
Although item ranking is not an accepted form of statistical data collection, the format was kept for multidimensional data collection and future reference.
MS conceptualized the project, screened records for eligibility, undertook data collection and analysis, created the Reference Manager output format, selected search terms, prepared the first draft of the manuscript, and participated in all revisions.
As previously suggested [ 49] we tried to minimize variability by having one person to coordinate the process of data collection and having a written reference of definitions based on the original articles of APACHE scores.
C-JW participated in the study with primary responsibility in conception and design drafting, overview the entire study, and data collection and analysis, literature review, reference search, draft writing and critically revised the manuscript and read proof of the final manuscript.
Early studies capitalized on 16S ribosomal data for bacterial characterizations because of the ease of data collection and the robust and growing reference databases.
In addition, for each study the following characteristics of study design were also retrieved: (1) needle gauge (21 gauge vs other size gauge); (2) guidance systems (with ultrasound or stereotactic guidance vs without image guidance); (3) prospective data collection, and (4) geographic location; (5) reference standard (histopathology only or not).
We also analyzed the effects of other covariates on DOR (ie, publication year, guidance systems, 21 or other size needle gauge, different reference standard, prospective data collection, and different geographic location).
