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
BACKGROUND AND
aimsThe present study conducted from March 2012 to July 2013 aimed to evaluate from echocardiographic point of view the effects of peripheral intravenous administration of mesenchymal stem cells (MSCs) in laboratory rabbits presenting 30 days old chronic myocardial infarction. MATERIAL AND
methods30 days after the induction of an acute myocardial infarction in 40 laboratory rabbits by direct ligation of the left anterior descending coronary artery at about 10 mm from the apex, we injected 1×106 MSCs in the auricular vein in a group of 30 rabbits, and a group of 10 rabbits were used as controls. 30 days after the injection of stem cells the left ventricular (LV) fractional shortening (FS) was evaluated by echocardiography and compared with the control rabbits.
resultsIn control rabbits, echocardiography revealed akinesis of apex, interventricular septum kinetics was also impaired, FS being approximately 6%. In 80% (24 rabbits) of the injected rabbits the FS of the LV was significantly greater than in the witness group (26+/-2%, p<0.0001). At 13.3% (4 rabbits) of the injected rabbits the FS of the LV showed no improvement in comparison with the control group (6.5+/-1%).
conclusionAn improvement of LV SF 30 days after MSCs were injected(p<0.0001) was noted. We have to further determine if this improvement of the LV function is correlated with any histopathological changes and if it is not lost in time. Also, further studies needs to evaluate if there is any significant change in the overall mortality.
