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
To investigate magnetic relaxation properties of the tailored contrast using paramagnetic gadolinium (Gd) chelates and superparamagnetic iron oxide particles (SPIOs) for cellular magnetic resonance imaging. The study included three different exposed environments with two different characteristic contrast agents which used gadodiamide (Omniscan; Gd-DTPA-BMA) and ferumoxide (Feridex; SPIO) in C6 brain cancer cells. Based on the minimal mutual interaction between these two agents in vitro, we examined the possibility of using mixture of cells that are separately labeled with two contrast agents or using concurrently labeled cells with different concentrations of the two contrast agents. In order to characterize the MR relaxation properties, aqueous solutions containing various concentrations of the two contrast agents were prepared as well as Ficoll solution suspensions containing labeled cells by different labeling schemes and subsequently investigated R
