ADRB2 polymorphisms and budesonide/formoterol responses in COPD.
Trial report in Chest, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 11 papers, 6 of them syntheses 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

Abstract
backgroundEffects of β(2)-adrenergic receptor gene (ADRB2) polymorphism on therapeutic responses to long-acting β(2)-adrenergic agonists have not been evaluated in long-term COPD trials. We aimed to investigate the effects of the ADRB2 Gly16Arg polymorphism on response to formoterol alone or in combination with the inhaled corticosteroid budesonide in patients with COPD.
methodsPatients ≥ 40 years of age with moderate to very severe COPD from the 12-month trial I (NCT00206167) or the 6-month trial II (NCT00206154) were randomly assigned to bid budesonide/formoterol pressurized metered-dose inhaler (pMDI) 320/9 μg or 160/9 μg, budesonide pMDI 320 μg + formoterol dry powder inhaler 9 μg (trial II), budesonide pMDI 320 μg (trial II), formoterol dry powder inhaler 9 μg, or placebo. The effect of Gly16Arg on predose FEV(1) and 1-h postdose FEV(1), exacerbations, diary variables, and adverse events were analyzed.
resultsNo significant interaction between genotype and treatment response was observed for predose (P ≥ .197) or postdose FEV(1) (P ≥ .125) in either pharmacogenetic study (n = 2,866). The number of COPD exacerbations per patient-treatment year was low and similar across genotypes for the active treatment groups (both studies). Percentages of patients with adverse events were similar across Gly16Arg genotype groups for each treatment.
conclusionTherapeutic response and tolerability to long-term treatment with formoterol alone or in combination with budesonide was not modified by ADRB2 Gly16Arg genotype in two large independent pharmacogenetic studies in patients with moderate to very severe COPD.
