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
Mechanical communications provide physical views to understand cell physiologies at large scale. Cell collective migration occurs often in vivo, of which the role of matrix tension force is largely unknown. Here to mimic in vivo conditions, we applied collective migration of renal epithelial MDCK cells on elastic matrix hydrogel containing bioactive materials of 50% Matrigel and 1 mg/mL type I collagen. MDCK cells were engineered with stable expression of ERK FRET (fluorescence energy resonance transfer) biosensor in regarding of ERK sensitivity in cell mechanical response. The results showed that matrix traction force derived from cells-generated contraction promoted epithelial sheet migration with higher ERK activity at the move front. Hydrogel crosslinking by glutaraldehyde blocked matrix traction transmission and then reduced ERK and epithelial collective migration. Integrin inhibition dramatically reduced collective migration but not local cell moving velocities, indicating integrin acting with mechanotransduction role at cells-hydrogel interface in orienting migration direction. Further experiments demonstrated that matrix traction force relied on activations of cellular mechanosensitive calcium channels, and ERK signal in promoting collective migration. In conclusion, matrix tension force derived from cell contractions facilitates epithelial collective migration through activating cellular mechanosensitive signals, in which integrin acts as mechanical transducer. This work highlights the role of matrix traction force in wound healing and tissue engineering.
