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
objectiveInvestigating the correlation between body mass index (BMI) and cognitive decline among elderly people in the Chinese community.
designA non-random sampling method was employed to conduct a cross-sectional, mixed methods survey among elderly individuals in the Chinese community.
settingThis research was conducted across the country, focusing on 20 distinct communities (2 rural and 18 urban) situated in the eastern, central and western parts of China.
participantsThe China Longitudinal Aging Study (cohort 1) and Shanghai Brain Aging study (cohort 2) were the sources of the present data. Cohort 1 consisted of 2947 individuals aged 60 and above, who were subjected to a comprehensive screening procedure encompassing a physical examination, medical background and initial evaluations of cognitive abilities through an in-person interview. Cohort 2 comprised an extra 226 older adults, including 54 patients with mild cognitive impairment (MCI) and 174 normal adults, and unlike cohort 1, all of them underwent T1 phase MRI scans. OUTCOME MEASURES: The cognitive abilities, BMI and structural magnetic resonance properties of elderly individuals in the Chinese community.
resultsIn cohort 1, we discovered that having a BMI below 18.5 kg/m
