Development of Novel Erythromycin Derivatives with Inhibitory Activity against Proliferation of Tumor Cells.
Article in PloS one, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
In our continuing structure-activity relationship study of a new class of erythromycin A (EM-A) derivatives with antiproliferative activity, a new series of de(N-methyl) EM-A dimers jointed by a four-atom linker, -CH2CH = CHCH2-, were prepared and their antiproliferative activity against three human tumor cell lines was evaluated by MTT assay. The most active EM-A dimer, compound 1b, that carrying C6 methoxyl groups was further investigated and showed potent antiproliferative activity in six other human tumor cell lines. Flow cytometry analysis of 1b treated HeLa and MCF-7 cells indicated that the four-atom EM-A dimers induced the SubG1 phase cell cycle arrest and cell apoptosis, in time- and dose-dependent manners. Further experiments including morphologic observation, DNA agarose gel electrophoresis, mitochondrial potential alternation and western blot analysis revealed that the antiproliferative mechanism may involve the induction of apoptosis in activating the mitochondrial pathway, and regulation of apoptotic proteins.
