1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Introduction: For evidence-based healthcare decisions, systematic reviews are essential, yet data extraction errors, often overlooked, pose a substantial threat. In the field of urology, there has been a notable increase in the number of reviews that are not subject to rigorous examination. This study pioneers a shift, investigating data reproducibility issues in urological systematic reviews, highlighting the critical need for scrutiny in evidence synthesis. Methods: This study examines data extraction errors in systematic reviews from 58 urology journals indexed in PubMed and Embase. Systematic reviews that include meta-analyses with randomized controlled trials will be selected. Data extraction will be carried out independently by two reviewers using standardized forms, followed by cross-verification with original sources. Errors will be categorized at the review, meta-analysis, and study levels. Statistical analyses will evaluate the prevalence of these errors and their impact on meta-analytic results. Sensitivity analyses will explore the effect of missing data on the study outcomes. Discussion: This study addresses the often-overlooked issue of data extraction errors in urology systematic reviews, which could impact the reliability of evidence-based decisions. By evaluating the reproducibility of data extraction, the study aims to enhance methodological rigor in urological reviews and improve the validity of conclusions drawn from evidence synthesis. Despite its limitations, this research will contribute valuable insights into the quality of systematic reviews and guide future improvements in evidence-based practice.
