[Risk factors for mortality in patients with chronic obstructive pulmonary disease].
Article in Atencion primaria, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 identify risk factors of mortality in patients with chronic obstructive pulmonary disease (COPD).
designA retrospective cohort study. LOCATION: Primary care setting in Lleida, Spain.
participants2.501 patients older than 40 years with at least a spirometry in the 24 months prior to the beginning of the study were followed for 3 years. MAIN MEASUREMENTS: The dependent variable was the overall mortality in the period 11/01/2010-10/31/2013; and the independents: spirometric parameters, severity (GOLD) and clinical variables. Their association with mortality was analyzed by calculating the adjusted odds ratio using a non-conditional logistic regression model.
resultsThe average age of 2.501 patients at the beginning of the study was 68.4 years (SD=11.6). 75.0% were males. 50.8% had a mild severity COPD, followed by moderate (35.3%), severe (9.4%) and very severe (4.4%). Mortality rate for the all period was 12.55%. The variables of the predictive model were: age, male sex, previous exacerbations, number of visits to primary care, comorbidity, smoking, severity of COPD (GOLD) and not receiving influenza vaccination, with an area under the ROC curve of 0.76.
conclusionsThis model, easy and quick to apply, would identify those patients at increased risk of mortality and who could benefit from preventive strategies to improve their survival.
