With the exception of two trials (one of 2 years' duration and one of 4 years' duration), the trials were 1 year or less in duration from start of treatment. Our analyses, focused on two time-points: 6 months and 1 year. The primary papers for each trial have been published [22e31] and their designs are summarized in Supplementary Table A1.
Respimat
The Respimat is a compact, handheld soft mist inhaler device designed for the delivery of respiratory medications. It generates a slow-moving, soft mist to facilitate inhalation of the medication by the user.

COPD Tiotropium Monotherapy Trials
With the exception of two trials (one of 2 years' duration and one of 4 years' duration), the trials were 1 year or less in duration from start of treatment. Our analyses, focused on two time-points: 6 months and 1 year. The primary papers for each trial have been published [22e31] and their designs are summarized in Supplementary Table A1.
Tiotropium/Olodaterol Inhalation for COPD
Eligible patients were randomized to receive one of three treatments:
tiotropium/olodaterol 2.5/5 μg, tiotropium/olodaterol 5/5 μg, or placebo, all
delivered once daily via the Respimat® (Boehringer
Ingelheim International GmbH, Ingelheim am Rhein, Germany) inhaler (
Throughout the 12-week treatment period, trial medication was self-administered
by the patient once daily between 7 a.m. and 10 a.m.; on test days,
administration of trial medication was performed under research staff
supervision. Patients continued with inhaled corticosteroids if taken at
baseline. Open-label salbutamol (albuterol) was provided as rescue medication
throughout the study.
The study was conducted in accordance with the Declaration of Helsinki and the
International Conference on Harmonization Tripartite Guideline for Good Clinical
Practice. Before the study started, the protocol was reviewed and approved by
the Institutional Review Boards, and all patients provided written, informed
consent.
Radiolabeled Aerosol Delivery Evaluation
Olodaterol Dose-Ranging Phase III Trials
The studies were carried out in accordance with the principles of the Declaration of Helsinki and the International Conference on Harmonisation Harmonised Tripartite Guideline for Good Clinical Practice, and written informed consent was obtained from each patient.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
