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

purposeProtein supplementation has been proposed as an effective dietary strategy for maintaining or increasing skeletal muscle mass and improving physical performance in middle-aged and older adults. Diabetes mellitus exacerbates muscle mass loss, leading to many older adults with type 2 diabetes mellitus (T2DM) experiencing sarcopenia, and vice versa. Our objective was to assess the impact of increased dietary protein intake on muscle mass, strength, physical performance, and the progression of T2DM in middle-aged and older adults diagnosed with this condition.

methodsA 12-week randomized, controlled, parallel pilot study was conducted with 26 patients diagnosed with T2DM and had either low muscle mass, or low muscle strength or poor physical performance (age > 55 years old), aiming to investigate the effects of a protein-rich diet in sarcopenic and metabolic markers. The control group received 0.8-1.0 g/kg/day, while the intervention group received 1.2-1.5 g/kg/day of protein respectively. Body composition, muscle mass/strength and biochemical parameters were measured before and after the intervention period.

resultsDifferent kinetics of skeletal muscle index (SMI), appendicular lean mass (ALM), hand grip strength (HGS), gait speed (GS) and standing balance (SB) (p < 0.05) were observed between two groups. Specifically, the intervention group showed a significant improvement in HGS (p < 0.001) and physical performance (timed-up-and-go, p < 0.001; GS, p = 0.011; SB, p = 0.022), while the control group had its ALM (p = 0.014), SMI (p = 0.011) and HGS (p = 0.011) significantly reduced. The kinetics of metabolic markers indices was similar for both groups.

conclusionCurrent recommendation for protein intake (0.8-1 g/kg/day) is certainly not enough to ameliorate the muscle mass loss in middle age and older adults' individuals with T2DM. In contrast, protein intake of 1.2-1.5 g/kg/day seems to be a more appropriate recommendation to combat upcoming sarcopenia, nonetheless the progression of T2DM was not interrupted.
