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 AND

objectiveA Likelihood ratio (LR) is a numerical measure of evidential value. Our objective was to use LRs to express the patient-specific evidential values of medical findings that best differentiate abusive versus non-abusive head trauma (AHT). We hypothesized that the evidential values of patients' AHT-related medical findings would be highly variable.

methodsWe analyzed existing, uniform, prospective, de-identified data regarding 973 acutely head-injured children < 3 years hospitalized for intensive care across 18 sites between 2011 and 2021; applied two different proxies for AHT and non-AHT ground truth; trained and validated statistical models that differentiate AHT versus non-AHT; and analyzed patient-specific LRs in a log

resultsThe two best performing statistical models revealed evidential (LLR) values for patient-specific, AHT-related medical findings that varied from modest (-1 to + 1) to relatively large (-2.5 to -1 and + 1 to + 3.5), and values that were misleading (AHT patients with LLR values indicative of non-AHT, and vice versa). A few non-AHT patients presented with misleading evidence that was moderately strong, with LLRs approaching + 3.

conclusionsReasonable medical certainty of AHT and non-AHT can be enhanced or limited by the highly variable evidential values of patients' most discriminating medical findings. Physicians can use available LRs to inform their AHT-related diagnostic reasoning, opinions, and testimony.
