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

Purpose: There has been significant progress in detecting Alzheimer's disease (AD) using retinal imaging. We developed an ensemble learning-based deep learning (DL) model, integrating different inputs from OCT for the detection of AD-dementia and early AD. Design: A retrospective multicenter case-control study. Participants: A total of 190 participants with AD-dementia and 623 cognitively normal controls were recruited from 2 cohorts in Hong Kong and Singapore as the training and internal validation sets. A total of 46 participants with AD-dementia, 79 participants with mild cognitive impairment (MCI), and 52 cognitively normal controls from 2 cohorts with amyloid-β status identified from positron emission tomography (PET) available in Hong Kong and Singapore as External-1 and External-2, respectively. Methods: We developed DL models for identifying AD-dementia versus cognitively normal and also tested the proposed ensemble model for classifying MCI (symptom-based) and AD-MCI (PET-based). Inputs were generated from a commercially available OCT device (Cirrus HD-OCT, Carl Zeiss Meditec, Inc), including optic nerve head (ONH)-centered and macula-centered Main Outcome Measures: Discriminative performance of the ensemble model for detecting AD-dementia, MCI, and AD-MCI. Results: For detecting AD-dementia, the ensemble model achieved the area under the receiver operating characteristic curve (AUROC) of 0.943 (95% confidence interval, 0.906-0.980), 0.786 (95% confidence interval, 0.673-0.899), and 0.795 (95% confidence interval, 0.716-0.874) in the internal validation, External-1, and External-2, respectively. For detecting AD-MCI defined by PET biomarkers, the ensemble model achieved AUROCs of 0.787 (95% confidence interval, 0.643-0.931) and 0.791 (95% confidence interval, 0.694-0.888) in the External-1 and External-2, respectively. Conclusions: Our proposed ensemble model, integrating multiple base models and inputs from OCT analysis, demonstrates strong potential for leveraging OCT imaging in detecting both AD-dementia and early-stage AD, enabling opportunistic screening for AD during ophthalmic visits.
