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

purposeChronic obstructive pulmonary disease (COPD) is usually recognized in its later stages, delaying therapeutic opportunities. Screening questionnaires have modest sensitivities and specificities. Adding questions about prior respiratory events might improve screening characteristics.

methodsUsing administrative data from all health care facilities in Olmsted County, Minnesota USA, we identified all adults with an initial diagnosis of COPD from 2005 through 2007. For each individual we identified all coded lower and upper respiratory events in the 2 years before and the 2 years after the COPD diagnosis and categorized them as probable or possible COPD exacerbations.

results356 women and 346 men (N = 702) with a mean age of 67.5 years and 66.6 years respectively had a first diagnosis of COPD during the study period. Respiratory events in the 2 years prior to a COPD diagnosis were common with a range of 0 to 16 events per individual and a mean (SD) of 2.04 (2.14), 1.38 (1.86) all of which were probable COPD exacerbations. Prediagnostic respiratory events were predictive of similar events in the post diagnostic period (odds ratio = 1.6, 95% confidence interval [CI] 1.3 to 1.8).

conclusionInquiring about the number and type of upper or lower respiratory events in the 2 past years may be a useful addition to the "screening" criteria to improve COPD identification, especially those at risk of frequent exacerbations.
