Hypocellularity and insufficient expression of angiogenic factors in implanted autologous bone marrow in patients with chronic critical limb ischemia.
Trial report in Heart and vessels, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The aim of this study was to identify the clinical parameters of absolutely poor-prognosis patients with chronic critical limb ischemia (AP-CLI). Sixteen no-option CLI patients with arteriosclerosis obliterans: ASO (nine) and non-ASO patients (seven) treated with bone marrow-mononuclear cell implantation (BMI) were analyzed. There were three AP-CLI patients (all ASO). The mRNA expression of several angiogenic factors in the implanted cells was analyzed in comparison with normal donor bone marrow. To observe the response of bone marrow components to hypoxia, normal bone marrow cells were cultured for 24 h in 2.5% O(2), and mRNA expression of angiogenic factors were measured. AP-CLI patients exhibited extraordinary low bone marrow cellularity as well as the percentage of CD34-positive cells. Among angiogenic factors, only VEGF expression was maintained in response to HIF-1, while other factors such as HGF, Ang-1, PLGF, and SDF-1 decreased in the implanted bone marrow cells of the patients with CLI compared to normal bone marrow cells. HIF-1 and all of the five angiogenic factors increased in vitro in response to hypoxia. Thus it is highly likely that angiogenic factors except VEGF do not respond to chronic ischemia in bone marrow in vivo. An organ-protection system against tissue ischemia may be applied for acute hypoxia, but it may be insufficient for chronic ischemia.
