Association between dietary magnesium intake and risk of cataract surgery: data from NHANES 2003-2008.

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
backgroundIn vitro and in vivo studies suggested that magnesium might have preventive effects on cataracts; however, the epidemiological evidence is limited. The objective of this study was to examine the association between magnesium intake and the odds of experiencing cataract surgery.
methodsA total of 8185 individuals aged ≥30 years were extracted from the National Health and Nutritional Examination Surveys (NHANES) in the cycles from 2003 to 2008. Magnesium intake was assessed using the 24-hour dietary recall method. The questionnaire determined whether participants had cataract surgery or not. Multivariable logistic regressions were performed to explore the associations between magnesium intake and the risk of cataract surgery.
resultsThe overall prevalence of cataracts was 13.4% (1094/8185). After controlling for potential confounders, we observed a significant inverse association between magnesium intake and cataracts, both as a continuous variable [odds ratio (OR): 0.78, 95% confidence interval (CI): 0.65-0.96, p = 0.013] and quartiles with the highest quartile compared to the lowest (OR: 0.78, 95% CI: 0.61-0.98, p trend = 0.027).
conclusionsThese results suggest that higher magnesium intake appears to be helpful for cataract prevention; however, additional prospective studies are required to ascertain whether magnesium intake can lead to a decrease in cataracts.
