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

Dileucine, a leucine-containing dipeptide, may enhance anabolic signaling more than leucine alone. This study examined postprandial plasma dileucine and leucine concentrations after ingesting animal- and plant- whole foods and their association with muscle protein synthesis rates (MPS). Secondary analysis was performed on plasma samples collected from two randomized controlled trials totaling 26 healthy adults (25 ± 4.3 y). Participants consumed low-fat pork (LFP), high-fat ground pork (HFP), complementary rice and beans (COMP), an iso-nitrogenous mixed nutrient beverage (ISO), or a carbohydrate control (CHO). Plasma concentrations and MPS was measured. Plasma dileucine increased significantly only after LFP ingestion (p < 0.05), with a greater 300-min iAUC compared to CHO (p = 0.038). Plasma leucine increased in all conditions except COMP and CHO with LFP demonstrating the highest concentrations (p < 0.05). A modest correlation was observed between dileucine Cmax and the change in MPS (ΔMPS; r = 0.436, p = 0.037), whereas leucine Cmax showed no significant association (r = 0.265, p = 0.102). Whole-food protein sources generally do not elevate plasma dileucine, except for LFP. While dileucine C
