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

Context: High protein diets (HPD), rich in branched-chain amino acids (BCAAs), are proposed to enhance glycemic control. The metabolic implications of elevated BCAAs in insulin resistance (IR) are unclear, but overactivation of ribosomal protein S6 kinase B1 (S6K1)-related signaling pathway may contribute to IR. Objective: To investigate the impact of 2 dietary protein interventions on IR and molecular signaling in skeletal muscle (acutely) and adipose tissue (18-week period) in overweight/obese individuals. Methods: The acute study included ingestion of 50 g protein (MPD), 100 g protein (HPD), or 50 g of protein with added fat (MPDAF) on 3 different occasions with muscle biopsies before and after. The 18-week analysis used a subset of data with available adipose tissue biopsies from a randomized, controlled, isoenergetic dietary intervention, focusing on the relevant HPD and control diets. Insulin sensitivity was assessed using labeled intravenous glucose tolerance tests acutely, and by euglycemic-hyperinsulinemic clamp in the 18-week intervention. Results: Inositol hexakisphosphate kinase 1 (IP6K1) and total AMP-activated protein kinase (AMPK) protein content significantly decreased following the HPD meal ( Conclusion: Key proteins implicated in intracellular insulin signaling were altered with an acute HPD meal (decreased IP6K1 and AMPK, increased pAkt/Akt2 activity), indicating potential enhancement of insulin-mediated glucose signaling at the molecular level. These findings suggest that, while systemic IR was unchanged, high protein intake may have beneficial effects on cellular insulin signaling.
