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
HMGB1, one of the most abundant nuclear non-histone proteins, also performs extracellular functions, and its nuclear export mechanisms have been extensively studied. Here, a novel mechanism of nuclear export for HMGB1 driven by lactylation is proposed. In addition, it is revealed that hypoxia-induced lactylation of HMGB1 facilitates its nuclear export in a complex with TIAR, promoting stress granule (SG) formation in the cytosol. Mass spectrometry revealed 12 lysine residues in HMGB1 undergoing lactylation, with K172 and K177 being the most susceptible. Functional studies using lysine-to-arginine mutants (K→R) demonstrated that lactylation at K177 is crucial for HMGB1-TIAR complex export, as K177R mutation completely blocked this export and subsequent SG formation. Notably, this lactylation-mediated mechanism is specific to hypoxic stress, while other stressors, such as sodium arsenite exposure and heat shock, triggered TIAR nuclear export and SG assembly independently of HMGB1. These findings reveal a previously unrecognized role of HMGB1 lactylation in mediating nuclear export and SG formation under hypoxia.
