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
Thioredoxin1 (TRX1) and telomerase are both attractive oncology targets that are tightly implicated in tumor initiation and development. Here, we reported that the 6-dithio-2-deoxyguanosine analog thiotert exhibits an effective cytotoxic effect on myelodysplastic syndromes (MDS) cell SKM-1 and lymphoma cell U-937. Further studies confirmed that thiotert effectively disrupts cellular redox homeostasis, as evidenced by elevated intracellular reactive oxygen species (ROS) levels, increased MnSOD, accelerated DNA impairment, and activated apoptosis signal. Mechanistically, our present study revealed that thiotert treatment effectively inhibited the function of the TRX1/TRXR1 system and telomerase reverse transcriptase (TERT), rendering oxidative damage and impairment of telomeres. Meanwhile, pharmacological administration of glutathione (GSH), N-acetylcysteine (NAC), and mitoquinone (MitoQ), or genetic overexpression of TRX1 or TERT in MDS and cells could dampen the toxicity caused by thiotert. Remarkably, the in vivo mouse model of MDS demonstrated that thiotert administration exhibited greater efficacy in tumor reduction compared to the conventional chemotherapy drug cytarabine. Collectively, these results provide experimental insights into the mechanism of thiotert-induced MDS and lymphoma cell death and unveil that thiotert may be an effective and promising new drug for future MDS and lymphoma treatment.
