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
aimThe aim of this study was to compare the accuracy and inter-account consistency of two Google Gemini-powered, user-facing workflows for dental trauma decision support: standalone Gemini chat and NotebookLM, a document-grounded workflow that generates responses grounded in uploaded European Society of Endodontology and International Association of Dental Traumatology guideline documents, when answering dichotomous (yes/no) clinical questions on the management of traumatized permanent teeth. METHODOLOGY: A cross-sectional simulation was conducted using 99 dichotomous (yes/no) questions derived from the European Society of Endodontology and International Association of Dental Traumatology guidelines. Three academic endodontists submitted each question to Gemini and NotebookLM using three independent Google accounts, generating 297 responses per workflow. Accuracy was defined as exact agreement with guideline-based answers, and consistency as the proportion of identical responses across the three trials. Statistical analyses included Wald and Wilson 95% confidence intervals, Fleiss' kappa for inter-account agreement, and Pearson's chi-squared tests to compare proportions.
resultsGemini demonstrated an overall accuracy of 83.83% (95% CI: 75.08-90.47) and a consistency of 74.74% (κ = 0.84). NotebookLM showed higher accuracy (92.93%; 95% CI: 85.97-97.11) and perfect consistency (100%; κ = 1.00). While the difference in accuracy did not reach statistical significance (p = 0.076), NotebookLM exhibited significantly greater consistency (p < 0.001).
conclusionsThe responses generated from the guidelines were highly consistent with both workflows. Document grounding may enhance repeatability and alignment with guideline-derived decision points for structured dichotomous inquiries, as evidenced by NotebookLM's ability to achieve complete inter-account consistency and to quantitatively increase accuracy. These results are the outcome of workflow-level benchmarking; therefore, clinical utility cannot be inferred solely from them; professional oversight and additional validation remain necessary before any clinical application.
