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

introductionRandomized interventional trials generally recruit highly selected patients. In contrast, long-term, noninterventional studies can reflect standard of care of real-life populations. DACCORD (Die ambulante Versorgung mit langwirksamen Bronchodilatatoren: COPD-Register in Deutschland [Outpatient Care With Long-Acting Bronchodilators: COPD Registry in Germany]) is an ongoing observational study, conducted in primary and secondary care in Germany, aiming to describe the impact of disease and treatments on real-life patients with chronic obstructive pulmonary disease (COPD).

methodsPatients had a clinical and spirometry diagnosis of COPD, were aged ≥40 years, and were initiating or changing COPD maintenance medication. The only exclusion criteria were asthma and participation in a randomized clinical trial. Exacerbation data were collected every 3 months. COPD medication, COPD Assessment Test, and forced expiratory volume in 1 second (FEV1) were recorded at the end of the 1 year period.

resultsIn the 6 months prior to baseline, 26.5% of the 3,974 patients experienced ≥1 exacerbation, compared with 26.1% over the 1-year follow-up (annualized rate 0.384). Importantly, only previous exacerbations and not poor lung function alone predicted an increased exacerbation risk. There was a general shift to lower disease severity from baseline to 1 year, predominantly as a consequence of a lower proportion of patients considered at high risk due to exacerbations. COPD Assessment Test mean change from baseline was -1.9, with 48.9% of patients reporting a clinically relevant improvement. Overall persistence to medication was high, with 77.2% of patients still receiving the same class of medication at 1 year.

conclusionDACCORD suggests that in clinical practice, the large majority of COPD patients are symptomatic but seldom exacerbate and that widely used tools and treatment recommendations do not reflect this fully.
