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
This study aimed to elucidate the molecular mechanisms by which PLD2 controls apoptosis and edema in pancreatic cells via the Nrf2/NF-κB pathway. AR42J rat pancreatic cells were treated with 10 nM mitomycin to create an in vitro pancreatitis model (model group), with a control group receiving phosphate-buffered saline. Cells were transfected with a PLD2 overexpression plasmid using Lipofectamine 3000, forming the PLD2 overexpression group. PLD2 protein expression was assessed by Western blotting, and TNF-α, IL-6, and IL-10 levels were measured by RT-qPCR. Nrf2/NF-κB protein expressions were also analyzed. Apoptosis and necrosis were evaluated using Annexin V-FITC/PI staining and the LDH release test. Cell edema was assessed by cell volume, ion content, and membrane damage. Western blotting was used to analyze pan-apoptosis-related proteins. PLD2 expression was lower in the model group compared to controls (P < 0.05) but higher in the PLD2 overexpression group (P < 0.05). TNF-α, IL-6, and IL-10 levels were elevated in the model group (P < 0.05) and reduced in the PLD2 overexpression group (P < 0.05). Nrf2 expression decreased in the model group but increased with PLD2 overexpression (P < 0.05). NF-κB expression increased in the model group but decreased with PLD2 overexpression (P < 0.05). Apoptosis and necrosis rates were higher in the model group (P < 0.05) but lower in the PLD2 overexpression group (P < 0.05). Cell volume, Na + content, and LDH release increased in the model group (P < 0.05) but decreased with PLD2 overexpression (P < 0.05). RIPK1 expression decreased in the model group (P < 0.05) but increased with PLD2 overexpression (P < 0.05). CASP8, FADD, and ZBP1 levels were higher in the model group (P < 0.05) and reduced with PLD2 overexpression (P < 0.05). PLD2 exerts a protective effect in acute pancreatitis by activating Nrf2 and inhibiting NF-κB, reducing apoptosis, cell swelling, and membrane damage. This highlights potential therapeutic targets for pancreatic inflammation.
