Asthma control in Canada: no improvement since we last looked in 1999.
Article in Canadian family physician Medecin de famille canadien, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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 determine whether asthma control in Canada had improved since the last major survey in 1999 by exploring how well patients' asthma was controlled, how much they knew about asthma control, and how they used health care resources.
designNational telephone survey of patients between April and August 2004.
settingCanada.
participantsEight hundred ninety-three adults 18 to 54 years old diagnosed with asthma more than 6 months before the survey.
main outcome measuresPatients' control of their asthma, patients' knowledge about asthma, the frequency and duration of periods of worsening asthma, and patients' use of health care resources to manage those periods.
resultsIn total, 26,210 households listed in a consumer database were contacted. Excluding ineligible households and households with a language barrier, a member of 13% of the households completed the 35-minute survey. Based on definitions in Canadian guidelines, 53% of patients had symptomatic uncontrolled asthma. In the previous year, almost all asthma patients had experienced worsening of symptoms that lasted on average 13.6 days for patients with uncontrolled asthma and 8.0 days for patients with controlled asthma (P < .02). Markedly more patients with uncontrolled asthma used health care resources for episodes of asthma than patients with controlled asthma did (72% vs 15% for urgent office visits, P < .01; 32% vs 3% for emergency department visits, P < .01; and 7% vs 0% for hospitalizations, P < .01) in the year before the survey. Patients were confused about the differences between reliever and controller medications. One third of patients claimed that no one had taught them about asthma medications, and one quarter said they had received no training on how to recognize the early signs of asthma worsening.
conclusionAsthma control and management remained suboptimal in Canada and relatively unchanged since the previous major survey in 1999.
