The prognosis of non-small cell lung cancer combined with chronic obstructive pulmonary disease: A systematic review and meta-analysis.
Synthesis in The clinical respiratory journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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
objectiveTo investigate the effect of non-small cell lung cancer (NSCLC) combined with Chronic Obstructive Pulmonary Disease (COPD) on prognosis, so as to provide help to clinical diagnosis and treatment.
methodsPubMed, Web of Science and the Medline were used to retrieve studies reported from 1950 to 2019. If the study reported the prognosis of COPD with NSCLC, the study was included and the relevant information was extracted and the data analyzed. The standard mean deviation (SMD) of 95% confidence interval was used in this meta-analysis.
resultsA total of 851 data studies were reviewed for eligibility, eventually, 12 case-control studies were included in this systematic review and meta-analysis. The sample sizes for company's studies of NSCLC ranged from 85 to 10 378, with a total number of 14 164, including 2450 COPD and 9395 Non-COPD. Meta-analyses showed that concomitant COPD was associated with poorer OS compared with patients without COPD (Fixed: HR: 1.16; 95% CI: 1.08-1.25. Random: HR: 1.07; CI: 0.92-1.24), with a significant heterogeneity across studies (I
conclusionOur study showed that patients with combined COPD had an impact on the prognosis and survival rate of SCLC patients.
