Increase in the Arterial Velocity Pulse Index of Patients with Peripheral Artery Disease.
Article in Pulse (Basel, Switzerland), 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRecently, a simple parameter calculated from the brachial pressure waveform recorded using an oscillometric device (arterial velocity pulse index [AVI]: ratio of the forward/reflected pressure wave amplitudes) has become available to assess the pathophysiological abnormalities associated with vascular damage. Peripheral artery disease (PAD) represents one of the disease entities associated with the advanced stages of atherosclerotic vascular damage. The present study was conducted to examine whether an increase in the AVI might be influenced by the presence of PAD. METHODS AND
resultsThe AVI was measured from oscillometric recordings of the brachial pressure waveform, and the ankle-brachial pressure index (ABPI) was determined by an oscillometric method. Study 1: In 341 consecutive patients admitted for the management of cardiovascular disease and/or cardiovascular risk factors, the ABPI and the AVI were measured simultaneously. An ABPI ≤0.90 was observed in 19 subjects, and logistic regression analysis revealed a significant association between AVI and ABPI ≤0.90 (odds ratio = 1.81; 95% confidence interval = 1.15-2.84;
conclusionPossible presence of PAD must be taken into account while applying the AVI for the assessment of vascular damage.
