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
Background: Pancreatic adenocarcinoma has a high mortality rate. Nanoliposomal irinotecan plus 5-fluorouracil and leucovorin (nal-IRI/FL) is the standard second-line chemotherapy after gemcitabine-based therapy. Although nanoliposomal irinotecan plus oxaliplatin, fluorouracil, and leucovorin (NALIRIFOX) has shown superior efficacy as first-line therapy over gemcitabine and nab-paclitaxel, its roles as second-line therapy remains undefined. Objectives: We aimed to compare the clinical outcomes and safety profiles of NALIRIFOX and nal-IRI/FL when used as a second-line treatment for patients with pancreatic adenocarcinoma who have progressed on a gemcitabine-based therapy. Designs: This was a single-center retrospective cohort study. Methods: We included patients with locally advanced or metastatic pancreatic adenocarcinoma who received NALIRIFOX or nal-IRI/FL following progression on first-line gemcitabine-based therapy from September 2020 to October 2024. Results: A total of 62 patients in the NALIRIFOX group and 131 in the nal-IRI/FL group were analyzed. Cumulative dose intensity ⩾80% over four cycles was achieved in 81.4% of the NALIRIFOX group and 73.1% of the nal-IRI/FL group ( Conclusion: NALIRIFOX provides superior PFS compared to nal-IRI/FL as second-line therapy for advanced or metastatic pancreatic cancer after gemcitabine failure. Although NALIRIFOX was associated with higher rates of hematologic and neurologic toxicities, they were manageable with careful monitoring.
