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

purposeIncreasing age, male gender, and metabolic syndrome are associated with kidney stone formation. As sex hormones change with age, gender, and metabolic syndrome, we hypothesized that sex hormones may underlie the physiologic changes affecting stone formation.

methodsWe analyzed the relationships between testosterone, estradiol, and history of kidney stones using data from 10,193 participants in the Continuous National Health and Nutrition Examination Survey (NHANES) database from 2013-2016. We performed logistic regression analysis to analyze the predictive value of low testosterone and low estradiol on the history of kidney stones in both males and females. Self-reported history of kidney stone diagnosis was the outcome.

resultsAfter adjusting for risk factors known to be associated with nephrolithiasis such as age, race, BMI, and medical comorbidities including: gout, angina, coronary disease, stroke, asthma, hypertension, and diabetes, multiple regression analysis demonstrated that there is no independent association between sex hormones (testosterone and estradiol) and history of kidney stones in either males or females.

conclusionsThere appears to be no association between sex hormones and history of kidney stones. Whether there is a more complex interaction of sex hormone levels and the shared association with factors such as metabolic syndrome requires additional investigation. Further studies matching menopausal status for women are necessary to further investigate the potential relationship between estrogen and kidney stones.
