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
Salicylidene acylhydrazide group synthetic compounds ME0053, ME005 and ME0192 are known for their iron chelating properties and due to these properties they are primarily used for blocking the bacterial type 3 secretory virulence system. On the other side, targeting the metabolic pathways of iron can provide new tools for cancer prognosis and treatment. Therefore, in this study, considering their iron chelating function, the effects of the compounds ME0053, ME0055 and ME0192 were investigated in SH-SY5Y neuroblastoma cell line. Iron chelating compounds are generally known to be effective in tumor development and metastasis by targeting iron in the cell. They can exert this effect through molecules such as cyclin, CDKs, as well as signaling pathways such as PI3K/AKT and ERK/MAPK. For this reason, we analyzed the effect of the iron chelating compounds of ME0053, ME0055 and ME0192 on cell viability and proliferation rate both through ERK/MAPK and PI3K/AKT signal paths, and through the oncogenic Speedy/RINGO protein that is likely to have a regulatory effect on these two signaling pathways. Apoptosis was also investigated by measuring the amount of active caspase-3, an apoptotic marker. Along with the decrease observed in the Speedy/RINGO level, it was observed that the PI3K/AKT and ERK/MAPK signaling were decreased. This suggests that ME0053, ME0055 and ME0192 compounds significantly decrease the Speedy/RINGO expression which has a regulatory effect on the ERK/MAPK and PI3K/AKT signaling. Besides, analyzing active caspase-3 levels showed that the compounds ME0053, ME0055 and ME0192 increased its level by 218%, 60% and 175% in SH-SY5Y cells, respectively. The results of this study will pave the way for better understanding of the regulation of cancer-related ERK/MAPK and PI3K/AKT pathways and the oncogenic Speedy/RINGO which potentially affects these pathways, through synthetic salicylidene acylhydrazides and their therapeutic use in cancer.
