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

Introduction. Bone-marrow-derived mesenchymal stem cells (MSCs) have been studied for treatment of myocardial infarction (MI). Since MSCs from older donors show quantitative and qualitative senescent changes, we hypothesized that a better outcome may be achieved if aged recipients are given MSCs obtained from young donors, rather than using their own autologous MSCs. Methods. In vitro studies compared properties of young and old MSCs. Aged rats randomized into 3 groups underwent coronary artery ligations and were then injected with either old (O) or young (Y) MSCs, or ligation alone. Echocardiography evaluated ejection fractions (EF). At 16 weeks, scar deposition was analyzed. Results. Old MSCs exhibited decreased cell viability, proliferation, and differentiation potentials. EF significantly improved early in both cell therapy groups (P < .05). However, at later stages of the study, group Y showed significantly better function which correlated with decreased scar deposition. Conclusions. The significant difference between young and old cells indicates the possible advantage for allotransplanting MSCs from young donors to elderly patients with MI.
