NOS-TLPlot

NOS-TLPlot visualizes Newcastle–Ottawa Scale (NOS) risk-of-bias assessments by converting raw star ratings into standardized risk categories and generating publication-ready visualizations for systematic reviews and meta-analyses.

Key Features:

• Traffic-light plots: Generates publication-ready traffic-light plots for clear interpretation of study-level risk-of-bias results.
• Twelve visualization types: Produces star distribution plots, traffic-light plots, radar charts, heatmaps, dot profiles, donut charts, and lollipop charts.
• Standardized risk categorization: Converts raw NOS star ratings into standardized risk categories.
• Customizable outputs: Supports customization of output themes, figure sizes, and export formats.
• Batch processing: Command-line interface enables batch processing and integration into reproducible analytical pipelines.

Scientific Applications:

• Systematic reviews: Enhances transparency, consistency, and efficiency of reporting study quality in systematic reviews involving non-randomized studies.
• Meta-analyses: Supports reproducible reporting of risk-of-bias results in meta-analyses of non-randomized studies.
