The Development of a COPD Exacerbation Recognition Tool (CERT) to Help Patients Recognize When to Seek Medical Advice.
Article in International journal of chronic obstructive pulmonary disease. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
introductionMany patients with chronic obstructive pulmonary disease (COPD) do not report exacerbations and may benefit from simple guidance about when to seek medical attention, so we developed a COPD Exacerbation Recognition Tool (CERT).
methodsThe study was run across three sites in China in patients who had an exacerbation within the previous year. Step 1: focus group qualitative study (total 48 patients) captured symptoms associated with an exacerbation. Step 2: cognitive debriefing to ensure items were appropriately worded. Step 3: 150 patients (69 years, 21% female, FEV
resultsFollowing Steps 1 and 2, 29 candidate items were selected for Step 3. Response rates with the two response options were very similar. There was minimal influence of demographic factors on response to the items. EFA using the 11 items with the highest response rates identified two principal factors, Factor 1: breathlessness and activity limitation (79.1% of variance), Factor 2: cough and sputum (20.9% of variance). Five items were selected for the CERT based on response rate and EFA factor loading: worsening cough, increased sputum volume, shortness of breath, laborious breathing, and limitation of motion. Sensitivity analysis suggested that worsening of two or more symptoms had good sensitivity and specificity for the presence of an exacerbation. DISCUSSION: The CERT is an evidence-based tool to provide patients with simple-to-follow guidance about when to seek medical attention when their COPD symptoms worsen.
