Odor identification and progression to dementia: The role of odor characteristics and set size.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionWe evaluated short versions of a 16-item odor identification (OID) test, with regard to their ability to identify individuals at high dementia risk.
methodsParticipants from the population-based SNAC-K study (
resultsLower OID scores were associated with an increased dementia hazard across all odor clusters. Lower performance in the high identifiability cluster showed the strongest association with dementia (hazard ratio = 1.39, 95% confidence interval [1.28-1.51]). Moreover, the high-intensity odor cluster showed a stronger association with dementia than the low-intensity cluster ( DISCUSSION: The findings suggest that the SST items differ with regard to their association with dementia and support using a reduced set size for clinical practice. Highlights: Odor identification (OID) items differ in their association with future dementia.Reduced OID set sizes render hazard ratios comparable to larger set sizes.Identifiability and perceptual characteristics of odors should be considered when designing dementia screening instruments.
