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

Using liver magnetic resonance imaging (R2-MRI) to quantify liver iron content (LIC), we conducted a prospective cohort study to determine the association between iron overload and adult allogeneic hematopoietic cell transplantation (HCT) outcomes. Patients received pretransplant ferritin measurements; patients with ferritin >500 ng/mL underwent R2-MRI. Patients were defined as no iron overload (N = 28) and iron overload (LIC >1.8 mg/g; N = 60). Median LIC in the iron-overload group was 4.3 mg/g (range, 1.9-25.4). There was no difference in the 1-year probability of overall survival, nonrelapse mortality, relapse, acute or chronic graft-versus-host disease, organ failure, infections, or hepatic veno-occlusive disease between groups. We also found no difference in the cumulative incidence of a composite end point of nonrelapse mortality, any infection, organ failure, or hepatic veno-occlusive disease (1-year cumulative incidence, 71% vs 80%; P = .44). In multivariate analyses, iron-overload status did not impact risks of overall mortality (relative risk = 2.3; 95% confidence interval, 0.9-5.9; P = .08). In conclusion, we found no association between pretransplant iron overload and allogeneic HCT outcomes. Future studies in this population should use LIC to define iron overload instead of ferritin.
