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
purposeTo investigate the cytotoxic and apoptotic effects of the combination of doxorubicin (Dox) and thymoquinone (TQ) on ovarian adenocarcinoma cells (OVCAR3) via the EGFR/FOXP3 signaling pathway.
methodsWe used human OVCAR3 and human skin keratinocyte cells (HaCaT). Different concentrations of TQ and Dox were applied to the cells for 24, 48, and 72 hours, and the cytotoxicity level was determined via the MTT method. Expression levels of EGFR/FOXP3 for cell proliferation and apoptosis were determined by quantitative reverse transcription polymerase chain reaction (RT-qPCR) and Western blot analysis. The colony counting was performed after DAPI staining, and the effect on cell proliferation was determined.
resultsCytotoxicity was found to be highest with TQ and Dox treatments, and cell migration was prevented, especially in the group that received combined TQ and Dox treatment. Moreover, using RT-qPCR analysis, activity in the EGFR and FOXP3 pathway was found to be downregulated the most with TQ, and the amount of protein decreased with TQ and Dox.
conclusionsThe findings showed that the greatest cytotoxic effect and the most apoptosis occurred during TQ treatment. Additionally, it was determined that a significant decrease in EGFR and FOXP3 levels occurred with the application of TQ and Dox.
