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

Mesenchymal stem cells (MSCs) effectively treat steroid-refractory acute graft-versus-host disease (aGVHD). However, their impact on patients with both steroid-refractory aGVHD (SR-aGVHD) and idiopathic pneumonia syndrome (IPS) is unclear. This retrospective study analyzed 24 patients who received MSCs as a secondary treatment for SR-aGVHD, including 6 who also had IPS. The 180-day overall survival rate was 52.0%, with a relapse rate of 13.3% and non-relapse mortality at 34.7%. The clinical course was compared between the six patients with concurrent IPS and SR-aGVHD who received MSCs and the 36 IPS patients who did not receive MSCs. The 6 MSC-treated patients had a higher 2-year overall survival rate than the control group, at 83.3% versus 61.1%, with all patients showing reduced oxygen requirements and improved imaging findings. Among the five patients who survived longer than 2 months after MSC therapy, the median time to complete oxygen therapy was 28 days, and steroid doses were reduced by 25% at the 2-month mark. Some patients showed improved pulmonary function after MSC therapy. These findings support MSCs as a promising treatment for SR-aGVHD and suggest potential benefits in IPS.
