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

introductionCentral hearing difficulties are a feature of Alzheimer's disease (AD) but not well captured by standard speech perception tests.

methodsWe developed a non-verbal dichotic listening test (NVDLT) based on everyday sounds, and compared this with a standard verbal dichotic listening test (VDLT) in 36 people with primary progressive aphasia (PPA), 18 with typical AD (tAD), 6 with right temporal-variant frontotemporal dementia (rtvFTD), and 29 cognitively-healthy controls. Daily-life hearing function was assessed using the modified Amsterdam Inventory for Auditory Disability and Handicap (mAIAD).

resultsOn NVDLT, all dementia groups except rtvFTD performed worse than controls; tAD, logopenic-variant PPA and nonfluent/agrammatic-variant PPA performed worse than rtvFTD. NVDLT performance predicted atrophy in the retrosplenial cortex and hippocampus. NVDLT score discriminated tAD patients from controls with near-perfect accuracy (area under the curve [AUC] = 0.99) and predicted daily-life hearing function (r = 0.57). DISCUSSION: NVDLT performance indexes daily-life hearing function and may aid dementia diagnosis, potentially in culturally-diverse populations.
