2. ccaR: A Package for Assessing Primary Study Overlap across Systematic Reviews in Overviews

Abstract

An overview of reviews aims to collect, assess, and synthesize evidence from multiple systematic reviews (SRs) on a specific topic using rigorous and reproducible methods. An important methodological challenge in conducting an overview of reviews is the management of overlapping data due to the inclusion of the same primary studies in SRs. We present a free, open-source R package called ccaR (https://github.com/thdiakon/ccaR) that provides easy-to-use functions for assessing the degree of overlap of primary studies in an overview of reviews with the use of the corrected cover area (CCA) index. A worked example with and without consideration of chronological structural missingness is outlined, illustrating the steps involved in, calculating the CCA index and creating a publication-ready heatmap. We expect ccaR to be useful for overview authors, methodologists, and reviewers who are familiar with the basics of R and contribute to the discussion on different methodological approaches for implementing the CCA index. Future research and applications could further investigate the functionality or potential limitations of our package and other potential uses.

Abstract

Objectives: The objective of this systematic review and meta-analysis is to evaluate the existing evidence and estimate the impact of phacoemulsification and intraocular lens implantation on the intraocular pressure (IOP) of subjects with exfoliation syndrome (XFS) or exfoliative glaucoma (XFG). Methods: In July 2024, an in-depth literature review across three databases was undertaken. This study focused only on adult patients with exfoliation who had not undergone previous ocular surgery. The primary outcome of interest was the mean IOP reduction at 6 and 12 months after uncomplicated phacoemulsification surgery. Results: This meta-analysis included one randomized controlled trial and eight observational studies, comprising 220 patients at 6 months and 430 patients at the 12-month time point, respectively. The mean IOP reduction after surgery was 3.43 mmHg (95% CI: −4.77 to −2.09) after 6 months and 2.75 mmHg (95% CI: −4.24 to −1.26) after 12 months. In both time points, there was no heterogeneity (I2 = 0), but the certainty of evidence following the GRADE evaluation was very low. Conclusions: The present meta-analysis demonstrates that phacoemulsification can significantly reduce IOP in exfoliation subjects 6 and 12 months after surgery. Nevertheless, significant limitations in included studies do not allow a precise and certain estimate of the magnitude of postoperative IOP lowering in exfoliation patients. Additional research is needed to confirm these results. [ABSTRACT FROM AUTHOR]

Abstract

Systematic reviews (SRs) have an important role in the healthcare decision-making practice. Assessing the overall confidence in the results of SRs using quality assessment tools, such as “A MeaSurement Tool to Assess Systematic Reviews 2” (AMSTAR 2), is crucial since not all SRs are conducted using the most rigorous methods. In this article, we introduce a free, open-source R package called “amstar2Vis” (https://github.com/bougioukas/amstar2Vis) that provides easy-to-use functions for presenting the critical appraisal of SRs, based on the items of AMSTAR 2 checklist. An illustrative example is outlined, describing the steps involved in creating a detailed table with the item ratings and the overall confidence ratings, generating a stacked bar plot that shows the distribution of ratings as percentages of SRs for each AMSTAR 2 item, and creating a “ggplot2” graph that shows the distribution of overall confidence ratings (“Critically Low,” “Low,” “Moderate,” or “High”). We expect “amstar2Vis” to be useful for overview authors and methodologists who assess the quality of SRs with AMSTAR 2 checklist and facilitate the production of pertinent publication-ready tables and figures. Future research and applications could further investigate the functionality or potential improvements of our package. [ABSTRACT FROM AUTHOR]
