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

objectivesLarge language models (LLMs) are increasingly being used today and are becoming increasingly important for providing accurate clinical information to patients and physicians. This study aimed to evaluate the effectiveness of generative pre-trained transforme-4.0 (ChatGPT-4.0), Google Gemini, and Microsoft Copilot LLMs in responding to patient questions regarding keratoconus.

methodsThe LLMs' responses to the 25 most common questions about keratoconus asked by real-life patients were blindly rated by two ophthalmologists using a 5-point Likert scale. In addition, the DISCERN scale was used to evaluate the responses of the language models in terms of reliability, and the Flesch reading ease and Flesch-Kincaid grade level indices were used to determine readability.

resultsChatGPT-4.0 provided more detailed and accurate answers to patients' questions about keratoconus than Google Gemini and Microsoft Copilot, with 92% of the answers belonging to the "agree" or "strongly agree" categories. Significant differences were observed between all three LLMs on the Likert scale ( P <0.001).

conclusionsAlthough the answers of ChatGPT-4.0 to questions about keratoconus were more complex for patients than those of other language programs, the information provided was reliable and accurate.
