Bone marrow graft as a source of allogeneic hematopoietic stem cells in patients undergoing a reduced intensity conditioning regimen.
Article in Bone marrow transplantation, 2014. 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
In an attempt to reduce the incidence of chronic GVHD (cGVHD) after reduced-intensity conditioning (RIC), we used BM instead of PBSC and added melphalan 100 mg/m(2) to the classical association of fludarabine, 30 mg/m(2)/day for 3 days and TBI, 200 cGy (FLUIM regimen). Between 2000 and 2012, 51 patients received BM with the FLUIM regimen (group A), and 124 received BM (n=22) or PBSC (n=102) with another RIC regimen (group B). Donors were siblings (n=123) or HLA-matched 10/10 unrelated (n=52). Full donor-type chimerism at day 100 was more often recorded in group A (86%) than in group B (62%); P<0.001. There was no difference between the two groups in terms of OS and EFS, acute GVHD, relapse and non-relapse mortality incidence. cGVHD occurred more often in group B (41%) than in group A (23%); P=0.021. In multivariate analysis, the two risk factors associated with the development of cGVHD were conditioning in group B (hazard ratio (HR)=2.871, 95% confidence interval (CI) (1.372-6.006); P=0.005) and CD34(+) count (HR=1.009, 95% CI (1.006-1.011); P<0.001). In conclusion, the FLUIM regimen followed by BM leads to more frequent full-donor chimerism and a reduced incidence of cGVHD without compromising relapse and survival.
