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

objectivesLarge population-based studies on the incidence and outcome of non-small cell lung cancer (NSCLC) are lacking in mainland China. This study aimed to investigate the NSCLC incidence, demographic features and survival as well as factors affecting survival of patients with NSCLC in Shanghai.

designProspective observational cohort study.

settingBaseline information was collected from Shanghai Health Information Network, which is based on the Health Information Systems from all the comprehensive hospitals and specialist hospitals qualified for cancer diagnosis in the Shanghai metropolitan area.

participantsAll NSCLC cases identified from the database between 2011 and 2013 were recruited (15,020 patients). MAIN

resultsThe crude and age-adjusted incidences of NSCLC were 54.20 per 100,000 people (55.90 per 100,000 for men, 52.39 per 100,000 for women) and 39.05 per 100,000 people (41.43 per 100,000 for men and 37.13 per 100,000 for women), respectively. The median survival time was 22.7 months (95% CI 21.8 to 24.2 months) with an overall 1-year survival rate of 71.8% (95% CI 69.8% to 73.8%). The 1-year survival rate was 96.5% (95% CI 94.0% to 98.6%) in patients with stage I NSCLC, 89.1% (95% CI 83.3% to 94.9%) in patients with stage II NSCLC, 78.8% (95% CI 74.1% to 83.5%) in patients with stage IIIa NSCLC and 58.9% (95% CI 56.1% to 61.7%) in patients with stage IIIb/IV NSCLC. Multivariate analysis showed surgical resection (HR=0.607, 95% CI 0.511 to 0.722) and chemotherapy (HR=0.838, 95% CI 0.709 to 0.991) significantly improved survival. Factors associated with poor survival included older age, male sex, larger tumour size, lymph node metastasis, distant metastasis and squamous cell carcinoma.

conclusionsA higher incidence and better survival rates for patients with NSCLC were identified when compared with previously published studies, which may provide evidence on the incidence and survival of NSCLC in China.
