Quality of AI chatbot-generated information on hypersensitivity pneumonitis for clinical and patient use.
Article in Sarcoidosis, vasculitis, and diffuse lung diseases : official journal of WASOG, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
aimHypersensitivity pneumonitis (HP) is a complex, immüne mediated interstitial lung disease in which accurate diagnosis and long term management require integration of clinical, radiologic, and exposure-related information. Patients increasingly use artificial intelligence (AI) based chatbots to obtain disease related information; however, the quality, readability, and patient usability of such content remain unclear. This study aimed to evaluate the quality, reliability, readability, and patient-centered usability of AI chatbot generated information on HP. MATERIALS AND
methodsUsing Google Trends, we identified four of the most frequently searched patient-oriented questions regarding HP: (1) What is HP and what causes it? (2) What are the clinical features of HP? (3) How is HP treated? (4) How is HP diagnosed? These questions were submitted verbatim to eight AI chatbots (ChatGPT-5.1, Claude 3, Microsoft Copilot, DeepSeek V3, Gemini Pro, Grok 4, Kimi K2, Perplexity AI). A total of 32 responses were independently evaluated in a blinded fashion by four pulmonology professors specializing in interstitial lung diseases. Content quality and reliability were assessed using DISCERN; understandability and actionability with PEMAT-P; global written readability with the Written Readability Rating (WRR); and structural readability with the Flesch-Kincaid Grade Level (FKGL).
resultsAll chatbot outputs required advanced literacy, with FKGL scores ranging from 20.17 to 29.07 and a mean of approximately 24-25, indicating college or postgraduate reading level. No chatbot produced content within the recommended patient-appropriate range (FKGL ≤ 8). WRR scores declined with increasing clinical complexity, from 67.85 for definitional content (Q1) to 51.227 for diagnostic explanations (Q4). DISCERN scores varied substantially across models (35.001-57.103), with most chatbots falling into the "fair-good" range, reflecting partially reliable but incomplete information. [..] Conclusion: AI chatbots can generate clinically rich explanations of HP but currently produce content that is too complex and insufficiently actionable for most patients. [..].
