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.

Abstract

High insulin concentrations increase blood flow in the leg, but it is unknown whether this effect is associated with a change in muscle blood volume. In the present study, we used positron emission tomography combined with inhalation of [15O]carbon monoxide to quantitate the effect of insulin on skeletal muscle blood volume in humans. The reproducibility of the method was determined from two consecutive measurements performed in the basal state in five normal subjects. The coefficient of variation of the repeated measurements was 3.0 +/- 1.8%. In 14 normal subjects [age 35 +/- 3 yr, body mass index 24.9 +/- 1.3 (SE) kg/m2], skeletal muscle blood volume was determined in the femoral region in the basal state and during euglycemic hyperinsulinemia (serum insulin 3,200 +/- 190 pmol/l). The mean muscle blood volume was 3.3 +/- 0.1 ml/0.1 kg muscle in the basal state. Insulin increased muscle blood volume by 9 +/- 2% to 3.6 +/- 0.2 ml/0.1 kg muscle (P < 0.01). The rate of whole body glucose uptake was 53 +/- 6 mumol.kg-1.min-1 and correlated with muscle blood volume during insulin stimulation (r = 0.65, P < 0.02). We conclude that high insulin concentrations exert a true vasodilatory effect in human skeletal muscle.
