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

backgroundSupervised exercise training (SET) is recommended as initial treatment to improve walking capacity in peripheral arterial disease (PAD) patients with intermittent claudication. Various mechanisms by which SET yields beneficial effects are postulated, however data regarding its influence on angiogenesis are scarce. Thus, we designed a prospective randomized controlled trial to study the impact of SET on markers of angiogenesis and endothelial function in PAD.

methodsForty PAD patients were randomized to SET on top of best medical treatment (SET+BMT) for 6 months versus best medical treatment (BMT) only. Endothelial progenitor cells (EPC) were assessed by whole-blood flow cytometry (co-expression of CD34+ CD133+ KDR+) and cell culture assays (endothelial cell-colony forming units, circulating angiogenic cells, migration assay) at baseline, 3, 6 and 12-months after inclusion. Changes of plasma levels of asymmetric dimethylarginine (ADMA), vascular endothelial growth factor (VEGF), stromal cell-derived factor-1 (SDF-1) and maximum walking distance were determined.

resultsEPC - measured by flow cytometric and cell culture techniques - increased significantly upon training paralleled by a significant decrease of ADMA when compared to the BMT group (p<0.05). Six months after training cessation, the beneficial effect of SET on EPC diminished, but maximum walking distance was significantly improved compared to baseline and controls (p<0.05). No significant changes were observed for VEGF and SDF-1 plasma levels in time course.

conclusionsSET increases circulating EPC counts and decreases ADMA levels reflecting enhanced angiogenesis and improved endothelial function, which might contribute to cardiovascular risk reduction.
