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

objectiveCognitive health in the elderly is linked to modifiable factors, including nutrition-related elements such as obesity, eating habits, and micronutrient deficiencies. The purpose of this study is to determine the association between serum magnesium levels and cognitive function among Palestinian elderly.

resultsA total of 200 older adults were included in the study (36.5% men and 63.5% women); the mean age was 64.6 ± 3.3 years. The mean cognitive function, as measured by the MoCA score, was 24.5 ± 3.66, whereas the average scores were 5.4 ± 1.19 for ADL and 6.2 ± 3.2 for IADL. The results indicated a substantial correlation between serum magnesium levels, IADL, smoking status, and cognitive performance. Sociodemographic characteristics, sleep quality, physical activity, body mass index, malnutrition, and adherence to the Mediterranean diet exhibited no significant correlation with serum magnesium levels. To conclude, serum magnesium levels were associated with smoking, cognitive function, and instrumental activities of daily living (IADL). Magnesium did not significantly correlate with Activities of Daily Living (ADL). These associations should be interpreted cautiously, as cognitive function is influenced by multiple additional factors not captured in this study.
