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.

2 · The registry

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

Allogeneic bone marrow transplantation is an essential therapy for acquired aplastic anemia and prognosis has recently improved. However, engraftment failure and graft-versus-host disease are potential fatal complications. Various risk factors for poor prognosis have been identified, such as patient age and human-leukocyte antigen disparity, but the relationship between donor age and prognosis is still unknown. Therefore, we performed a cohort study to compare the prognosis of unrelated bone marrow transplantation from younger and older donors using the registry database in Japan. We evaluated 427 patients (age 16-72 years) with aplastic anemia who underwent bone marrow transplantation from younger (≤39 years, n=281) or older (≥40 years, n=146) unrelated donors. Overall survival of the older donor group was significantly inferior to that of the younger donor group (adjusted hazard ratio 1.64; 95% confidence interval 1.15-2.35; P<0.01). The incidence of fatal infection was significantly higher in the older donor group (13.7% vs. 7.5%; P=0.03). Primary engraftment failure and acute graft-versus-host disease were significantly more frequent in the older donor group (9.7% vs. 5.0%; adjusted hazard ratio 1.30; P=0.01, and 27.1% vs. 19.7%; adjusted hazard ratio 1.56; P=0.03, respectively). Acute graft-versus-host disease was related to a worse prognosis in the whole cohort. This study showed the inferiority of older donors in aplastic anemia; thus, donor age should be considered when multiple donors are available. A large-scale prospective study is warranted to establish a better donor selection algorithm for bone marrow transplantation in aplastic anemia.
