Comorbidity and survival of Danish lung cancer patients from 2000-2011: a population-based cohort 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
objectiveTo examine lung cancer survival and the impact of comorbidity in the Central Denmark Region from 2000 to 2011.
methodsWe performed a population-based cohort study of lung cancer patients diagnosed during four 3-year calendar periods (2000-2002, 2003-2005, 2006-2008, and 2009-2011) in the Central Denmark Region. The Danish National Registry of Patients was used to identify 9,369 incident lung cancer patients, and to obtain data on their Charlson comorbidity index score, categorized as no (score = 0), medium (score = 1-2), or high (score ≥3) level comorbidity. We calculated 1- and 5-year survival in different calendar time periods overall, and by age, sex, and level of comorbidity, and used Cox regression to compute mortality rate ratios (MRR) for each level of comorbidity versus no comorbidity in different calendar time periods.
resultsOverall 1-year survival increased from 31% in 2000-2002 to 37% in 2009-2011, while the 5-year survival increased from 10% in 2000-2002 to predicted 13% in 2009-2011 with the largest improvement observed for women and patients less than 80 years. The adjusted 1-year MRR in patients with high comorbidity compared with those without comorbidity was 1.23 (95% confidence interval [CI]: 1.05-1.46) in 2000-2002 and 1.35 (95% CI: 1.17-1.56) in 2009-2011. The corresponding adjusted 5-year MRRs were 1.21 (95% CI: 1.04-1.40) in 2000-2002 and 1.26 (95% CI: 1.11-1.42) in 2009-2011.
conclusionLung cancer patients' survival increased from 2000 to 2011 in the Central Denmark Region, most prominently for women under 80 years and patients with no, or medium level of comorbidity. Their prognosis remained nonetheless dismal with overall 5-year survival of 13%, and comorbidity remained a negative prognostic factor.
