Clinical impact of pre-transplant pulmonary impairment on survival after allogeneic hematopoietic stem cell transplantation.
Article in Pathology oncology research : POR, 2012. 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
We retrospectively analyzed the clinical outcomes of patients with pulmonary impairment before undergoing allogeneic hematopoietic stem cell transplantation (HSCT) for the first time. Among 297 evaluable patients who underwent their first HSCT, 23 had restrictive, obstructive or mixed ventilatory impairment (n = 9, 13 and 1, respectively). Males predominated among the patients with pulmonary impairment (p = 0.037) and received a reduced intensity conditioning (RIC) regimen more frequently, although the difference did not reach statistical significance (p = 0.05). Among 23 patients with pulmonary impairment, 9 underwent post-transplant pulmonary function tests and obstructive ventilatory impairment progressed only in 2 patients, both of whom developed bronchiolitis obliterans. Kaplan-Meier estimates of 3-year overall (OS) among patients with and without pulmonary impairment were 57% and 47%, respectively, and those of relapse-free survival (RFS) were 70%, and 68%, respectively, with no significant differences between the groups (OS, p = 0.235; RFS, p = 0.287). The rates of non-relapse mortality also did not significantly differ (p = 0.835). Our results suggest that allogeneic HSCT is safe for patients with pulmonary impairment. The lower frequency of fatal pulmonary complications after HSCT and the RIC regimen might contribute to favorable survival rates.
