Impact of Female Sex on the Susceptibility to Hypernatremia Among Older Community-Dwelling Individuals in Japan.

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
purposeOlder individuals are at high risk for hypernatremia. However, actual data on serum sodium levels and differences between the sexes remain unclear in the older Japanese population. This study aimed to describe the data regarding serum sodium level and hypernatremia prevalence and to investigate whether female sex is associated with an increased risk of hypernatremia. PATIENTS AND
methodsWe retrospectively analyzed the data of adults aged ≥65 years without severely reduced kidney function who underwent an annual health checkup in 2019. Serum sodium levels were investigated as the outcome and corrected for glucose, if necessary. Clinical characteristics were compared between women and men.
resultsIn the 903 participants consisting of 273 women and 630 men who were enrolled in this study, the overall prevalence of hypernatremia, defined as a serum sodium level ≥145 mmol/L, was 12.5%. Female participants showed significantly more frequent hypernatremia than male participants (17.6% vs 10.3%,
conclusionOne-eighth of the older community dwellers in Japan exhibits hypernatremia after an overnight fast, and female sex is a significant risk factor. Since sCr is a surrogate of muscle mass, smaller muscle mass possibly mediates the association between female sex and hypernatremia.
