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

Small cell lung cancer (SCLC) is a high-grade neuroendocrine tumor characterized by rapid growth, early metastatic spread, and poor prognosis. This study aimed to explore the prognosis factors of survival in Chinese SCLC patients.A total of 78 patients with stage IIIA SCLC (mean age: 53.9 years, 65 males and 13 females) were enrolled in this retrospective study. At least of 5 years follow-up was performed.The survival time of these patients ranged from 1 month to 66 months with a median survival time of 11 months. Kaplan-Meier method with log-rank test was performed and showed that survival time in patients with tumor size ≤4 cm (median: 16 months) was significantly longer (P < .001) than that in patients with tumor size > 4 cm (median: 8 months); the median survival time of the patients with single lymph node metastasis was significantly longer than that in patients with multiple lymph node metastasis (P = .043). Combined multiple lymph node metastasis and tumor size >4 cm presented the worst survival outcome than others. Multivariate analysis by Cox Hazard model shows that the lymph node metastasis and tumors size were prognostic factors independent of age, sex, smoke, surgery, and treatment regimen (P < .05).Results showed that larger tumor size and multiple lymph node metastasis were associated with the poor survival in SCLC.
