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

objectiveUnderstanding how well older individuals with suspected cognitive impairment are functioning within the real-world environment can have important implications for diagnosis and treatment. To evaluate whether an individual is experiencing functional limitations suggesting the presence of mild cognitive impairment (MCI) or dementia, we establish diagnostic cutoff scores for the informant version of the Instrumental Activities of Daily Living-Compensation (IADL-C) scale.

methodInformants of research (n = 488) and clinical (n = 119) samples of participants designated as healthy older controls, MCI, or dementia completed the IADL-C. Receiver operating characteristic curve analyses and diagnostic statistics were used to determine optimal cutoffs on the IADL-C for both the 27-item IADL-C and an 11-item short form created using item-level analysis.

resultsThe optimal cutoff scores that maximized the Youden Index for the research sample long-form were 1.41 in distinguishing cognitively healthy versus MCI participants, and 3.60 in distinguishing dementia from MCI participants, favoring specificity for the clinical sample, the optimal cutoffs were 1.32 and 3.06, yielding higher sensitivity.

conclusionsThese cutoff scores, when used as a screening measure or combined with other clinical and cognitive measures, may be useful for understanding whether an individual may be experiencing functional difficulties in everyday life consistent with a diagnosis of MCI or dementia.
