Comparison of brachial artery vasoreactivity in elite power athletes and age-matched controls.
Article in PloS one, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06387758 (Low Systemic/High Local Exercise Load in Pediatric Sickle Cell Disease), which is not on this map. Cited by 3 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.

Abstract
unlabelledElite endurance athletes typically have larger arteries contributing to greater skeletal muscle blood flow, oxygen and nutrient delivery and improved physical performance. Few studies have examined structural and functional properties of arteries in power athletes. PURPOSE: To compare the size and vasoreactivity of the brachial artery of elite power athletes to age-matched controls. It was hypothesized brachial artery diameters of athletes would be larger, have less vasodilation in response to cuff occlusion, but more constriction after a cold pressor test than age-matched controls.
methodsEight elite power athletes (age = 23 ± 2 years) and ten controls (age = 22 ± 1 yrs) were studied. High-resolution ultrasonography was used to assess brachial artery diameters at rest and following 5 minutes of forearm occlusion (Brachial Artery Flow Mediated Dilation = BAFMD) and a cold pressor test (CPT). Basic fitness measures included a handgrip test and 3-minute step test.
resultsBrachial arteries of athletes were larger (Athletes 5.39 ± 1.51 vs. CONTROLS: 3.73 ± 0.71 mm, p<0.05), had greater vasodilatory (BAFMD%: Athletes: 8.21 ± 1.78 vs. CONTROLS: 5.69 ± 1.56%) and constrictor (CPT %: Athletes: -2.95 ± 1.07 vs. CONTROLS: -1.20 ± 0.48%) responses, compared to controls. Vascular operating range (VOR = Peak dilation+Peak Constriction) was also greater in athletes (VOR: Athletes: 0.55 ± 0.15 vs. CONTROLS: 0.25 ± 0.18 mm, p<0.05). Athletes had superior handgrip strength (Athletes: 55.92 ± 17.06 vs. CONTROLS: 36.77 ± 17.06 kg, p<0.05) but similar heart rate responses at peak (Athletes: 123 ± 16 vs. CONTROLS: 130 ± 25 bpm, p>0.05) and 1 minute recovery (Athletes: 88 ± 21 vs. CONTROLS: 98 ± 26 bpm, p>0.05) following the step test.
conclusionElite power athletes have larger brachial arteries, and greater vasoreactivity (greater vasodilatory and constrictor responses) than age-matched controls, contributing to a significantly greater VOR. These data extend the existence of an 'athlete's artery' as previously shown for elite endurance athletes to elite power athletes, and presents a hypothetical explanation for the functional significance of the 'power athlete's artery'.
