Trace Element Concentration and Cognitive Dysfunction in Elderly Residents in Birjand.
Article in Current Alzheimer research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundTrace elements were suggested to have a main role in modulating cognitive function. However, there are several controversial findings regarding the association between serum trace element concentration and cognitive function in patients with cognitive disorders.
methodsThus, this study aimed to evaluate the changes in serum trace element concentrations in elderly with cognitive dysfunction versus the participants with normal cognitive function. This crosssectional study included 191 older adults over 60 years from Birjand County, Iran. Participants were assessed for cognitive performance and serum trace elements concentration, including aluminum (AL), cobalt (Co), cadmium (Cd), Chrome (Cr), copper (Cu), Iron (Fe), magnesium (Mg), manganese (Mn), selenium (Se) and zinc (Zn). Our findings showed no significant difference in the serum concentration of AL, Co, Cr, Zn, Fe, Mg, Mn, and Se of elderly with cognitive dysfunction versus the subjects with normal cognitive function.
resultsHowever, the concentration of Cu significantly increased in the serum of the elderly with cognitive dysfunction versus participants with normal function. In conclusion, our study indicated an increase in the serum concentration of Cu in the elderly with cognitive dysfunction in the sample of the Birjand Longitudinal Aging Study.
conclusionHowever, due to the main limitations of our study, including low sample size and crosssection design, these findings should be interpreted with caution.
