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

rationaleThe effects of c-kit(POS) cardiac progenitor cells (CPCs, and adult cell therapy in general) on left ventricular (LV) function have been regarded as modest or inconsistent.

objectiveTo determine whether 3 CPC infusions have greater efficacy than 1 infusion. METHODS AND

resultsRats with a 30-day-old myocardial infarction received 1 or 3 CPC infusions into the LV cavity, 35 days apart. Compared with vehicle-treated rats, the single-dose group exhibited improved LV function after the first infusion (consisting of CPCs) but not after the second and third (vehicle). In contrast, in the multiple-dose group, regional and global LV function improved by a similar degree after each CPC infusion, resulting in greater cumulative effects. For example, the total increase in LV ejection fraction was approximately triple in the multiple-dose group versus the single-dose group (P<0.01). The multiple-dose group also exhibited more viable tissue and less scar, less collagen in the risk and noninfarcted regions, and greater myocyte density in the risk region.

conclusionsThis is the first demonstration that repeated CPC administrations are markedly more effective than a single administration. The concept that the full effects of CPCs require repeated doses has significant implications for both preclinical and clinical studies; it suggests that the benefits of cell therapy may be underestimated or even overlooked if they are measured after a single dose, and that repeated administrations are necessary to evaluate the effectiveness of a cell product properly. In addition, we describe a new method that enables studies of repeated cell administrations in rodents.
