Randomised, double-blind, placebo-controlled crossover study to investigate different dosing regimens of olodaterol delivered via Respimat® in patients with moderate to severe persistent asthma.
Trial report in Respiratory research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01311661 (Phase II, Randomised, Double-Blind, Cross-over Study to Compare the 24-hour FEV1-time Profile of Orally Inhaled Olodaterol, Delivered With the Respimat® Inhaler, After 3 Weeks of Olodaterol Once Daily Medium Dose, Twice Daily Low Dose and Placebo or After 3 Weeks of Once Daily High Dose, Twice Daily Medium Dose and Placebo Administration in Patients With Moderate to Severe Persistent Asthma), which is not on this map.

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.

Abstract
backgroundA Phase II, multicentre, randomised, double-blind, placebo-controlled, crossover trial comparing the 24-h forced expiratory volume in 1 s (FEV1) time profile after 3 weeks' treatment with once-daily (QD) or twice-daily (BID) olodaterol (at the same total daily dose) versus placebo delivered via Respimat® in patients with moderate to severe asthma.
methodsPatients were randomised to different sequences of olodaterol with 2-week washout, either as a total daily dose of 5 μg (5 μg QD [AM] or 2.5 μg BID) or placebo, or 10 μg (10 μg QD [AM] or 5 μg BID) or placebo. Primary end point was FEV1 area under the curve from 0 to 24 h (AUC0-24) response (defined as change from study baseline FEV1) after 3 weeks. Key secondary end points were FEV1 AUC0-12 and AUC12-24 responses.
resultsTwo hundred and six patients received treatment. All olodaterol treatments demonstrated statistically significant improvements in FEV1 AUC0-24 response at 3 weeks versus placebo (p < 0.0001); adjusted mean treatment difference versus placebo was 0.191 L for olodaterol 2.5 μg BID (95 % confidence interval [CI] 0.152, 0.229), 0.150 L for 5 μg QD (95 % CI 0.111, 0.189), 0.228 L for 5 μg BID (95 % CI 0.190, 0.266) and 0.209 L for 10 μg QD (95 % CI 0.170, 0.247). These results were supported by the key secondary end points. Olodaterol 5 μg QD provided numerically lower mean values for 24-h bronchodilation than olodaterol 2.5 μg BID (p = 0.0465), with no statistically significant difference between treatment with olodaterol 10 μg QD and 5 μg BID. No relevant differences in morning and evening peak expiratory flow or Asthma Control Questionnaire scores at 3 weeks were observed between different doses and regimens. Adverse events were generally mild to moderate and comparable between groups.
conclusionsAll doses and dose frequencies provided adequate 24-h bronchodilation superior to placebo. Based on the results of this study, it would be reasonable to include both posologies of 5 μg olodaterol daily (5 μg QD or 2.5 μg BID, both delivered in two puffs per dose from the Respimat® inhaler) in subsequent studies. Further studies are necessary to confirm the optimum dosing regimen in asthma. No safety concerns were identified.
