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
backgroundNutritional status and systemic immune-inflammatory activity reflect dynamic interactions between tumor biology and host response and are closely implicated in cancer progression. However, the comparative prognostic utility of nutritional and immune-inflammatory indices in the post-recurrence setting of pancreatic cancer remains unclear. This study investigated the prognostic interaction between established nutritional and immune-inflammatory markers in patients with recurrent pancreatic cancer following pancreatectomy.
methodsA total of 120 patients who developed recurrence following pancreatectomy for pancreatic cancer were retrospectively analyzed. Nutritional status was assessed using serum albumin, the geriatric nutritional risk index (GNRI), and the prognostic nutritional index (PNI). Immune-inflammatory status was evaluated using the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII). The prognostic significance of these indices for post-recurrence survival was examined, and their discriminative performance was compared.
resultsAmong the nutritional markers, the GNRI demonstrated the highest discriminative ability for post-recurrence survival, while the SII showed the strongest performance among immune-inflammatory indicators. Both GNRI and SII were significantly associated with survival after recurrence. Stratification based on the combined GNRI and SII classification revealed that the integrated model provided superior prognostic discrimination compared with either marker alone. Multivariate analysis confirmed that the combined GNRI–SII classification was an independent prognostic factor in patients with recurrent pancreatic cancer (p = 0.005).
conclusionsPatients presenting with a low GNRI and high SII at the time of recurrence experienced significantly poorer survival compared with other combinatorial groups. The combined assessment of GNRI and SII represents a practical and potentially valuable tool for prognostic stratification and may assist in guiding optimal therapeutic decision-making in recurrent pancreatic cancer.
