Serum vitamin D levels correlate with metabolic abnormalities and microalbuminuria in diabetic patients: a restricted cubic spline dose-response analysis.

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
Objective: This study aimed to explore the dose-response associations of serum vitamin D levels with metabolic parameters and microalbuminuria (ACR) in diabetic patients, to identify the critical clinical threshold of vitamin D for renal and metabolic benefits, and to clarify the population heterogeneity of these associations stratified by microalbuminuria status. Methods: A total of 485 diabetic patients were retrospectively enrolled and divided into four groups according to vitamin D quartiles: Q1 (≤32.37 nmol/L, Results: The median serum vitamin D level was 45.7 nmol/L in this cohort, with a vitamin D deficiency/insufficiency rate of 75.1%. Serum vitamin D levels were significantly inversely correlated with HbA1c ( Conclusion: Vitamin D levels are negatively associated with metabolic abnormalities and microalbuminuria in a dose-dependent manner, suggesting that patients with microalbuminuria may have a stronger association, warranting further investigation in prospective studies.
