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
objectiveThis study aims to assess the therapeutic efficacy and safety of nivolumab combined with chemotherapy as a first-line treatment for advanced or metastatic gastric cancer, specifically comparing the outcomes of oxaliplatin-based versus albumin-bound paclitaxel (nab-paclitaxel)-based therapies.
methodsWe retrospectively analyzed 93 patients with advanced gastric cancer or gastroesophageal junction adenocarcinoma treated at the First Medical Center of Chinese PLA General Hospital from September 2017 to November 2022. Patients were categorized into the nivolumab + oxaliplatin (N-OX group) or nivolumab + nab-paclitaxel (N-AP group) based on the chemotherapy regimen. Progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and safety were evaluated as endpoints.
resultsAt the end of the follow-up period on September 31, 2023, we reported an ORR of 65.6% and DCR of 95.7% across all patients. The median PFS was 8.4 months, with no significant difference between the N-OX and N-AP groups (median, 7.8 vs 9.5 months; P = 0.450). Notably, patients with diffuse gastric cancer in N-AP group showed a 44.7% reduction in tumor progression risk compared with the N-OX group (P = 0.046). The overall safety profile was acceptable in two groups.
conclusionsOur study suggested that nivolumab combined with chemotherapy was effective and safe as a first-line intervention for advanced gastric cancer. While both oxaliplatin and nab-paclitaxel regimens showed similar efficacy, the nab-paclitaxel may offer additional benefits for patients with diffuse gastric cancer. Further research is encouraged to confirm these findings and refine treatment strategies.
