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

BACKGROUND/

objectivesInitial data analysis (IDA) is essential for valid and reproducible statistical analyses, but existing IDA frameworks were primarily developed for single-study datasets. Cancer registries (CRs) are extensive data systems characterized by continuous updates, repeated data extraction, multiple analytical uses, and evolving classification systems, which create requirements not addressed by existing IDA frameworks. This study aims to develop a structured IDA framework adapted to CRs.

methodsWe conceptualized IDA in CRs as a process spanning three data states: operational registry data, the extracted dataset and the analysis-ready dataset. The framework was developed by adapting existing IDA principles to the CR setting and organizing them into four stages: metadata, cleaning, screening, and reporting. The approach is based on predefined and versioned rule sets, structured recording of data processing, and metadata-based linkage between dataset definitions, data cleaning rules, screening outputs, the final report and dataset. A demonstrative survival dataset from the Slovenian Cancer Registry was used to illustrate implementation.

resultsThe framework is represented by the item set defining the activities and expected outputs of the structured IDA process in CRs. In the use case, metadata specified the dataset scope, intended use, variables, coding context, and applicable rules. Execution of the selected rules produced an analysis-ready dataset with traceable data cleaning steps, documented eligibility decisions, screening outputs describing the general and analysis-specific data properties, and the IDA report intended for external researchers to be delivered alongside the data.

conclusionsThe proposed framework extends existing IDA approaches to meet the specific requirements of CRs. It supports consistent dataset preparation and with that improves transparent and reproducible data use.
