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

Background: Accumulating evidence suggests that niacin interventions may have a beneficial role in preventing ophthalmological microangiopathic remodeling. This study aimed to assess the impact of niacin intake on the presence of diabetic retinopathy (DR) in two independent Mediterranean cohorts of individuals with type 1 diabetes (T1D) and type 2 diabetes (T2D). Methods: Cross-sectional, population-based epidemiologic study. A total of 243 individuals with T1D, and 291 individuals with T2D. All participants underwent an eye examination. Dietary niacin intake was analyzed using a validated Spanish 101-items food frequency questionnaire consumption. The association between niacin intake and DR was assessed using a multivariate logistic regression, with potential non-linear associations further explored through restricted cubic spline regression. DR diagnostic was established via multifield stereoscopic retinal photography, in accordance with the international consensus on DR. Results: DR was identified in 103 out of 243 individuals with T1D and 144 out of 291 with T2D. Dietary niacin intake did not differ within the study groups according to DR status. Multivariate logistic regression models also revealed no association between dietary niacin intake and DR. As previously described, the duration of diabetes for T1D and T2D, [OR (95%CI), 1.02 (1.01-1.03), and 1.02 (1.02-1.03), respectively] and glycated hemoglobin (HbA1c) [OR (95%CI), 1.16 (1.09-1.24), and 1.14 (1.09-1.18), respectively] were identified as the main determinant variables for DR in both groups. Conclusions: We found that dietary niacin intake was not associated with the presence of RD in subjects with either T1D or T2D. Further research is needed to better understand the potential role of niacin in the development or prevention of DR.
