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
Pancreatic cancer exhibits high mortality and morbidity, and the prognosis worsens when recurrence occurs. Current standard treatments, such as chemotherapy or radiation, show limited efficacy in recurrent end-stage pancreatic cancer. A man in his 70s visited our facility with a diagnosis of recurrent end-stage pancreatic cancer (Stage Ⅳ) with multiple metastases to mesenteric and paratracheal lymph nodes and the right liver lobe. Due to the severe side effects, chemotherapy was not an option anymore. After apheresis, a combined immune cell-based therapy incorporating α-galactosylceramide (α-Galcer)-pulsed dendritic cell (DC) vaccine therapy into Wilms' tumor 1 (WT-1) vaccine and natural killer (NK) cell therapy was initiated. On completing a nearly three-month course of seven administrations of each therapy, follow-up positron emission tomography-computed tomography (PET-CT) scans showed the regression of the recurrent cancer region as well as the metastasis regions. Meanwhile, chemotherapy was not provided. A significant decrease in tumor-associated markers (i.e., CA19-9, from 88.3 to 54.4 U/mL; DU-PAN-2, from 267 to 76 U/mL) and improvement in the immune profile status (i.e., neutrophil percentage decreased from 68% to 64.2%; lymphocyte percentage increased from 18% to 25.6%, and neutrophil-lymphocyte ratio decreased from 3.8 to 2.5) were observed. His performance status initially deteriorated (to 1 or 2), but improved to 0 without any disability and limiting daily life. Any adverse events or side effects associated with the immune cell-based therapy were not recorded. This single-patient case report demonstrated the clinical potential of incorporating α-Galcer DC vaccine therapy into WT-1 vaccine and NK cell therapy to enhance the anti-tumor effects of immune cell-based therapy. While this case report provided significant insights to facilitate future research, further observations and investigations are warranted with the ultimate goal of improving outcomes in patients with advanced cancers.
