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

Methodological standards of existing clinical AI research remain poorly characterized and may partially explain the implementation gap between model development and meaningful clinical translation. This systematic review aims to identify AI-based methods to predict outcomes after moderate to severe traumatic brain injury (TBI), where prognostic uncertainty is highest. The APPRAISE-AI quantitative appraisal tool was used to evaluate methodological quality. We identified 39 studies comprising 592,323 patients with moderate to severe TBI. The weakest domains were methodological conduct (median score 35%), robustness of results (20%), and reproducibility (35%). Higher journal impact factor, larger sample size, more recent publication year and use of data collected in high-income countries were associated with higher APPRAISE-AI scores. Most models were trained or validated using patient populations from high-income countries, underscoring the lack of diverse development datasets and possible generalizability concerns applying models outside these settings. Given its recent development, the APPRAISE-AI tool requires ongoing measurement property assessment.
