Diagnostic interpretation of corneal tomography using a multimodal large language model (ChatGPT).

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.
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
Purpose: To describe the use of a commercially available general large language model (LLM) in extracting and interpreting several key metrics from entire raw corneal tomography (Pentacam) reports for the diagnosis of corneal disorders. Observation: Anonymized corneal tomography biometry reports of 50 eyes of 50 patients with healthy corneas (n = 28), keratoconus (n = 20) and post-surgical ectasia (n = 2) were analyzed by a multimodal general LLM. System prompts were used to extract flat and steep keratometry values (K1 and K2, respectively), astigmatism, pachymetry values and provide an overall diagnosis. Accuracy of data extraction was 100 % across all metrics and the model provided a diagnosis in agreement with the two observers in all eyes. Pachymetry and maximum keratometry values were the most common metric used to formulate the diagnosis and was cited in all eyes. This was followed by specifically citing the highest elevation map values (88 %) and degree of astigmatism (74 %). Conclusion and importance: In this proof-of-concept study, a commercially available multimodal LLM was able to extract data from raw corneal tomography reports with high accuracy and with retention of spatial context, and formulated correct diagnoses with excellent proficiency. This study demonstrates the use of emerging LLMs as diagnostic adjuncts through the synthesis of multimodal data.
