Validation of the Quick Mild Cognitive Impairment Screen in an American Sample of Patients With Mild Cognitive Impairment and Mild Dementia.
Article in International journal of geriatric psychiatry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveEarly detection of cognitive impairment is critical for patient outcomes, yet cognitive impairment is under identified in primary care settings largely due to time constraints. The Quick Mild Cognitive Impairment (Qmci) screen was developed to address the need for a short cognitive screening instrument (< 5 min) that is sensitive to early cognitive change but has not been validated in the United States (US). The objective of this study was to examine the classification accuracy of the Qmci in participants from two memory specialty (e.g., secondary outpatient) clinics in the US.
methodsParticipants were 152 older adults: 87 participants were cognitively normal (CN), 48 were diagnosed with mild cognitive impairment (MCI) and 17 were diagnosed with mild dementia (DEM). Classification accuracy of the Qmci and Mini Mental State Examination (MMSE) were compared in participants with and without cognitive impairment.
resultsThe Qmci demonstrated higher classification accuracy in differentiating CN from cognitively impaired participants (i.e., MCI and DEM) (AUC = 0.82) than the MMSE (AUC = 0.77). The optimal cut-off score for the Qmci was < 67, which achieved a sensitivity of 79% and specificity of 80%. The optimal MMSE cut-off score was < 27, which achieved a sensitivity of 97% and specificity of 43%.
conclusionsThe Qmci is a valid cognitive screening instrument for detecting early stages of cognitive impairment in memory clinic samples in the US. Its short administration time and increased specificity for detecting MCI make it an attractive option for use in primary care settings. Further validation of the Qmci is needed, specifically within primary care settings.
