Management, morbidity and mortality of COPD during an 11-year period: an observational retrospective epidemiological register study in Sweden (PATHOS).

The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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

Abstract
backgroundChronic obstructive pulmonary disease (COPD) is one of the most common causes of mortality and a major contributor to morbidity. Longitudinal clinical practice data yielding information on the characteristics of the disease, its natural course, and management are limited.
aimsTo investigate and describe the COPD population from a nationwide perspective during an 11-year period (1999-2009) with a focus on management, co-morbidity, and mortality.
methodsThis observational retrospective epidemiological study linked electronic medical records data from patients with COPD in primary care to mandatory Swedish hospital, drug and Cause of Death registry data from 1999 to 2009 (PATHOS).
resultsA total of 21,361 patients with a COPD diagnosis were included (mean age 68.0 years, 53% females). The proportion of patients diagnosed in primary care increased from 59% in 1999 to 81% in 2009 and the mean age at diagnosis decreased from 73 to 66 years. The number of exacerbations decreased from 3.0 to 1.3 and COPD-related hospitalisations decreased from 1.02 to 0.20 per patient per year. Prescriptions of long-acting muscarinic antagonists and fixed combinations of inhaled corticosteroid/long-acting β2-agonist inhalers increased from 0% to 36% and 37%, respectively. The most common co-morbidities were hypertension, heart failure, ischaemic heart disease, and diabetes. Overall life expectancy was 8.3±6.8 years shorter in patients with COPD than in the general population, and all- cause mortality was 3.5 times higher.
conclusionsManagement of COPD in Sweden has improved during the 11-year study period. Despite this, patients with COPD have a substantially reduced life expectancy than the general population.
