Trial reportEmergency medicine journal : EMJ2007
A randomised, double-blind, placebo-controlled study to evaluate the role of formoterol in the management of acute asthma.
Trial report in Emergency medicine journal : EMJ, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
aimTo evaluate the efficacy and tolerability of formoterol delivered by Aerolizer in the emergency department.
methodsA single-centre, double-blind, randomised, placebo-controlled, parallel group study was conducted in patients seeking emergent care for an acute exacerbation of asthma. Patients were randomly assigned to one of two groups: group 1 (salbutamol), receiving a total dose of 600 microg salbutamol (200+200+200) delivered by a meter-dose inhaler into a spacer device as two puffs at 20 min intervals; and group 2 (formoterol), receiving formoterol 24 microg (12+12) as two dry powder capsules each containing 12 microg of formoterol via Aerolizer at 20 min intervals. The peak expiratory flow rate (PEFR) was measured at baseline and 5 min after the second and third doses.
results60 subjects receiving salbutamol (n = 28) or formoterol (n = 32) completed the study. Age, gender, baseline PEFR, duration of asthma and previous medication were balanced between the two groups. Mean PEFR increased significantly over baseline values in both the salbutamol and formoterol groups (63% in the salbutamol group, p = 0.001, and 55% in the formoterol group, p = 0.001). No significant difference was observed in the increase in PEFR between the groups (p = 0.99, 95% CI -29.62 to 29.59). The proportion of patients reporting adverse events was similar in the two groups.
conclusionFormoterol was found to be well tolerated and as effective as salbutamol in the management of acute asthma. Further studies are needed to follow the patients after discharge from the emergency room to compare the long-term effect of formoterol on patients' stability.
