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
objectivesPancreatic ductal adenocarcinoma (PDAC) is one of the most malignant digestive tract tumors with a poor prognosis and high recurrence rate. Recently, ferroptosis resistance has been found in PDAC. However, the underlying mechanism of ferroptosis resistance has not been fully elucidated. Cytochrome P450 2J2 (CYP2J2) is the main enzyme which mediates arachidonic acid to produce epoxyeicosatrienoic acids (EETs) in human tissues. It has been reported that EETs involve in the development of cancer, while the roles of EETs in PDAC and ferroptosis remain unclear.This study aims to explore the effect of CYP2J2/EETs on ferroptosis of human pancreatic ductal adenocarcinoma cells PANC-1 cells and the underlying mechanisms.
methodsThe tumor tissues and para-carcinoma tissues of 9 patients with PDAC were collected and the expression of CYP2J2 was detected with real-time PCR and Western blotting. Enzyme-linked immunosorbent assay (ELISA) was used to detect the level of 8,9-dihydroxyeicosatrienoic acid (8,9-DHET), and the degradation product of 8,9-epoxyeicosa-trienoic acid (8,9-EET). PANC-1 cells were used in this study. The ferroptosis inducer erastin was used to induce ferroptosis. The intracellular long-chain acyl-CoA synthetase 4 (ACSL4) protein level, lactate dehydrogenase (LDH) activity, malondialdehyde (MDA) content, Fe
resultsHigh expression of CYP2J2 was found in PDAC, accompanied by an increased level of 8,9-DHET. The 8,9-EET pretreatment significantly attenuated the PANC-1 cell death induced by erastin. The 8,9-EET reduced the Fe
conclusionsCYP2J2/EETs are highly expressed in PDAC tissues. EETs inhibit the ferroptosis via up-regulation of GPX4 in a PPARγ-dependent manner, which contributes to the ferroptosis resistance of PDAC.
