Women Have Greater Endothelin-B Receptor Function and Lower Mitochondrial Capacity Compared to Men With Type 1 Diabetes.
Article in The Journal of clinical endocrinology and metabolism, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
contextType 1 diabetes (T1D) negatively affects both the endothelin system and muscle oxidative capacity. The endothelin pathway is a critical regulator of microcirculatory function and may exhibit sexual dichotomy by which healthy premenopausal women have greater endothelin-B receptor (ETBR) function compared to men. Moreover, T1D may differentially alter muscle oxidative capacity in men and women; however, whether ETBR function is impaired in women compared to men with T1D and its relationship with muscle oxidative capacity has yet to be explored.
objectiveThe purpose of this investigation was to determine if ETBR-mediated dilation is impaired in women compared to men with T1D and if this is related to their skeletal muscle oxidative capacity.
methodsMen (n = 9; glycated hemoglobin A1c [HbA1c] = 7.8 ± 1.0%) and women (N = 10 women; HbA1c = 8.4 ± 1.3%) with uncomplicated T1D were recruited for this investigation. Near-infrared spectroscopy (NIRS) and intradermal microdialysis (750 nM BQ-123 + ET-1 [10-20-10-8 mol/L]) were used to evaluate skeletal muscle oxidative capacity and assess ETBR-mediated vasodilation, respectively.
resultsSkeletal muscle oxidative capacity was significantly lower (P = .031) in women compared with men with T1D. However, ETBR-mediated dilation induced a significantly greater (P = .012) vasodilatory response in women compared to men with T1D, and the area under the curve was negatively associated with skeletal muscle oxidative capacity (r = -.620; P = .042).
conclusionCompared to men with uncomplicated T1D, muscle oxidative capacity was lower and ETBR-mediated vasodilation was higher in women with uncomplicated T1D. ETBR-induced vasodilatory capacity was inversely related to skeletal muscle oxidative capacity, suggesting there may be compensatory mechanisms occurring to preserve microvascular blood flow in women with T1D.
