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

purposeVitamin C is a fundamental antioxidant with important metabolic actions in several biological processes. Patients with type 2 diabetes (T2D) are exposed to oxidative stress as a consequence of an increased production of reactive oxygen species (ROS). The aims of the present study were to estimate the prevalence of vitamin C deficiency in ambulatory patients with T2D, to study the relationship between vitamin C levels and cardiovascular diseases and to correlate the consumption of fresh fruit and vegetables with vitamin C levels and the presence of cardiovascular diseases.

methodsVitamin C levels, determined by high-performance liquid chromatography (HPLC), and consumption of fresh fruit and vegetables, assessed by a food frequency questionnaire, were measured in 200 outpatients with T2D. All other laboratory variables were measured by standard methods. The association between vitamin C and cardiovascular diseases was assessed by multivariable logistic regression analysis.

resultsVitamin C deficiency was found in 12.2% of the subjects. Vitamin C levels and consumption of fresh fruit and vegetables were lower in subjects with cardiovascular diseases. Consumption of fresh fruit and vegetables was associated with higher levels of vitamin C. In the multivariable analysis, vitamin C was independently associated with cardiovascular diseases.

conclusionIn conclusion, our study suggests that vitamin C may have an inverse relationship with cardiovascular diseases. Intake of vitamin C from fresh fruit and vegetables could play a protective role.
