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
The pluripotent mouse embryonic stem cell (mESCs) can transit into the totipotent-like state, and the transcription factor DUX is one of the master regulators of this transition. Intriguingly, this transition in mESCs is accompanied by massive cell death, which significantly impedes the establishment and maintenance of totipotent cells in vitro, yet the underlying mechanisms of this cell death remain largely elusive. In this study, we found that the totipotency transition in mESCs triggered cell death through the upregulation of DUX. Specifically, R-loops are accumulated upon DUX induction, which subsequently lead to DNA replication stress (RS) in mESCs. This RS further activates p53 and PMAIP1, ultimately leading to Caspase-9/7-dependent intrinsic apoptosis. Notably, inhibiting this intrinsic apoptosis not only mitigates cell death but also enhances the efficiency of the totipotency transition in mESCs. Our findings thus elucidate one of the mechanisms underlying cell apoptosis during the totipotency transition in mESCs and provide a strategy for optimizing the establishment and maintenance of totipotent cells in vitro.
