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
ERK is a key signaling mediator controlling both proliferation and lineage specification during embryo development. How ERK choreographs differentiation and proliferation to achieve balanced developmental outcomes in lineages with variable ERK activities remains unclear. To investigate this, we established multiplex quantitative live-cell imaging to track human pluripotent stem cell differentiation into mesendoderm (ME), a lineage specified by gastrulation morphogens and dependent on high ERK activity. We found that distinct morphogen combinations generate varying ERK activity levels, which correlate with heterogeneous ME fate choices despite relatively uniform cell cycle dynamics. To dissect how heterogenous ERK levels directly modulate and coordinate ME differentiation and proliferation, we engineered a synthetic spectrum of titrated ERK activities. Our results showed that ERK fine-tunes ME differentiation potential and cell division speed under nonoverlapping activity ranges, enabling quantitative control of ME fate specification without major effect on cell cycle progression. Mechanistically, this uncoupling stems from differential transcriptional and translational sensitivities of ME-specifying genes versus cell cycle genes to ERK input. Together, our findings reveal how a single signaling pathway quantitatively balances differentiation and proliferation during lineage commitment and embryogenesis.
