Simultaneous assessment of blood flow changes in femoral artery and skeletal muscle microvasculature using pulsed-wave and power Doppler ultrasonography.
Article in European journal of applied physiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
purposeThe purpose of this study was to evaluate blood flow changes in femoral artery and skeletal muscle microvasculature during intermittent submaximal isometric knee extension.
methodsSeventeen healthy young males (19.7 ± 1.2 years) performed intermittent (5 s on, 5 s off) isometric knee extension. Five contractions were performed at each force level of 10%, 30%, 50%, and 70% of maximal voluntary contraction (MVC) at random with a 10-min rest between sets. We measured right femoral artery blood flow by pulsed-wave Doppler ultrasonography and intramuscular blood flow in the vastus lateralis of the right mid-thigh by power Doppler ultrasonography, simultaneously. Both femoral artery and intramuscular blood flow were normalized by the peak value for each participant and represented as %Peak. Time-to-peak was defined as the time from the end of exercise to the peak.
results%Peak of femoral artery blood flow was significantly higher than that of intramuscular blood flow at the baseline and following contractions at 10% MVC (P < 0.01). The time-to-peak during the post-exercise of intramuscular blood flow was significantly longer than that of femoral artery blood flow following contractions at 70% MVC (P < 0.01).
conclusionsThese results indicate that blood flow increases appeared slowly in skeletal muscle microvasculature than in femoral artery after intermittent submaximal isometric knee extension, suggesting that differences in vascular reactivity and blood flow regulation could exist between femoral artery and skeletal muscle microvasculature in healthy young males.
