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

backgroundMild cognitive impairment (MCI) is a common disorder among the geriatric population (GP). MCI induces adverse effects on life quality by disrupting of natural aging process, daily activities, and memory. This systematic review and meta-analysis study aimed to investigate the global prevalence of MCI in GP with an emphasis on associated influential factors.

methodsElectronic databases of PubMed, Scopus, WoS, Embase, ScienceDirect, and Google Scholar were systematically searched (by November 2024) using the MeSH-based keywords. Collected references were imported into the Citation Management Software of EndNote (v.8) for duplicate detection. Paper screenings and quality assessments were applied based on the inclusion and exclusion criteria. Then, eligible papers were gathered and data analysis was performed using CMA software (v.2).

resultsIn the review of 51 eligible studies (n = 287,689 elderly individuals), the global prevalence of mild cognitive impairment in geriatric population was found 23.7% (95%CI:18.6-29.6). According to the meta-regression analysis, following the increase in sample size and year of paper publication, the mild cognitive impairment index decreased and increased, respectively. Besides, age, educational level, and depression status were considered the most critical influential factors of mild cognitive impairment in geriatric population.

conclusionAccording to the relatively high prevalence of mild cognitive impairment in geriatric population, determination of proper health strategies seems necessary for diagnosis and treatment of mild cognitive impairment along with awareness and management of associated consequences in geriatric population. CLINICAL TRIAL NUMBER: Not applicable.
