1 · What the graph read from it

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.

2 · The registry

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

The current study aimed to investigate baseline anemia in patients with stage IV non-small cell lung cancer (NSCLC) and its relationship with clinicopathological features and prognosis. The clinical data of 4,874 patients with stage IV NSCLC were analyzed. The incidence of baseline anemia was observed. The relationship between baseline anemia and clinicopathological features was analyzed. Kaplan-Meier method and multivariate COX regression model were used to analyze the relationship of baseline anemia and prognosis of patients with NSCLC. Anemia classification was based on the criteria established by the National Cancer Institute (NCI). The mean hemoglobin (Hb) was 123.32±20.31 g/l in patients with stage IV NSCLC. The prevalence of baseline anemia was 32.09%, among which 19.08, 10.79, 1.91 and 0.31% had mild, moderate, severe, and life-threatening anemia, respectively. The prevalence of baseline anemia was higher in patients who were >60 years old, male, had smoking history, exhibited squamous cell carcinoma and bone metastasis, and the difference was statistically significant. Univariate analysis indicated that patients without anemia had longer overall survival (OS) compared with patients with baseline anemia (median OS: 28.0 months vs. 17.4 months, P<0.001). As the grade of anemia rises, it was indicated that OS became shorter. Patients with anemia grade 0 had the longest OS (median OS: 28.0 months), followed by patients with anemia grades 1 and 2 (median OS: 17.5 months). The patients with anemia grades 3 and 4 had the shortest OS (median OS: 8.6 months; P<0.001). Multivariate analysis demonstrated that baseline anemia and anemia grade were independent prognostic factors in patients with stage IV NSCLC. In conclusion, baseline anemia and anemia grade are independent prognostic factors in patients with stage IV NSCLC.
