Sex and Age but Not Body Mass Index (BMI) Predict Serum Retinol Binding Protein 4 (RBP4) and Transthyretin (TTR) Concentrations.

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
Increased serum concentrations of retinol (vitamin A) and its binding protein retinol binding protein 4 (RBP4) have been linked to progressive obesity, type 2 diabetes, and reduced liver or kidney function. It has been suggested that body mass index (BMI) and serum RBP4 concentrations correlate. Whether this correlation is due to obesity or associated disorders such as insulin resistance or steatotic liver disease is not known. In circulation, RBP4 forms a complex with transthyretin (TTR). Whether the formation of the RBP4-TTR complex is altered with progressive obesity remains to be determined. The goal of this study was to establish whether serum RBP4, retinol, and TTR concentrations change with BMI in a population without diabetes or organ impairment. Fasting serum concentrations of RBP4, TTR, and retinol were measured by LC-MS/MS in individuals with a broad range of BMI (21-56 kg/m
