Efficacy of ramucirumab and subsequent nivolumab therapy in patients with advanced gastric cancer: A retrospective study.

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
Nivolumab monotherapy is a standard treatment of metastatic gastric cancer, and this type of cancer involves vascular endothelial growth factor (VEGF) signaling in the tumor immunological environment. The subgroup analysis of the ATTRACTION-2 trial revealed that prior treatment with ramucirumab (RAM), a VEGF inhibitor, affected the therapeutic effect of nivolumab. The present retrospective study aimed to review patients with metastatic gastric cancer who were treated with paclitaxel (PTX) and RAM followed by nivolumab. A total of 29 patients with metastatic gastric cancer were treated with PTX + RAM as second-line treatment, followed by nivolumab monotherapy as third-line treatment. The therapeutic efficacy of nivolumab was compared in 13 patients with progression-free survival (PFS) of <5 months and 16 patients with PFS ≥5 months after PTX + RAM therapy. The present study included 22 male and seven female patients, with a median age of 68 years (range, 45-82 years). Human epidermal growth factor receptor 2 positivity was observed in six patients. The disease control rate was 62.1%. The PFS and overall survival (OS) were 4.4 and 11.9 months, respectively. Patients with PFS ≥5 months after PTX + RAM therapy showed better outcome in both PFS (5.3 months vs. 2.8 months, P=0.039) and OS (6.9 months vs. 15.2 months, P=0.066) after nivolumab treatment than patients with PFS of <5 months after PTX + RAM therapy. However, no significant relationship was observed between the outcome of first-line treatment and nivolumab. The therapeutic effect of nivolumab was associated with prior PTX + RAM treatment in advanced gastric cancer.
