Utility of COPD Assessment Test (CAT) in primary care consultations: a randomised controlled trial.
Trial report in Primary care respiratory journal : journal of the General Practice Airways Group, 2013. 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
backgroundOne of the aims of the COPD Assessment Test (CAT) is to aid communication between the physician and patient about the burden of chronic obstructive pulmonary disease (COPD) on the patient's life.
aimsTo investigate the impact of the CAT on the quality of primary care consultations in COPD patients.
methodsPrimary care physicians across Europe conducted six consultations with standardised COPD patients (played by trained actors). Physicians were randomised to see the patient with the completed CAT (CAT+ arm) or without (no CAT arm) during the consultation. These were videoed and independent assessors scored the physicians on their ability to identify and address patient-specific issues such as depression (sub-score A); review standard COPD issues such as breathlessness (sub-score B); their understanding of the case (understanding score); and their overall performance. The primary endpoint was the global score (sub-scores A+B; scale range 0-40).
resultsA total of 165 physicians enrolled in the study and carried out six consultations each; 882 consultations were deemed suitable for analysis. No difference was seen between the arms in the global score (no CAT arm 20.3; CAT+ arm 20.7; 95% CI -1.0 to 1.8; p=0.606) or on sub-score A (p=0.255). A statistically significant difference, though of limited clinical relevance, was observed in mean sub-score B (no CAT arm 8.8; CAT+ arm 9.6; 95% CI 0.0 to 1.6; p=0.045). There was no difference in understanding score (p=0.824) or overall performance (p=0.655).
conclusionsThe CAT is a disease-specific instrument that aids physician assessment of COPD. It does not appear to improve detection of non-COPD symptoms and co-morbidities.
