Study summary

Patients who are suffering from Chronic Obstructive Pulmonary Disease (COPD) had a decreased level of physical activity which is consequentially related to another acute exacerbation event. In this study, we selected patients from those who were admitted for acute exacerbation of COPD, evaluated physical activity by accelerometer (wearable multisensory armband devices) to find out the correlation between physical activity in COPD acute exacerbation patients.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Nov 2017 (actual). Primary completion is estimated for Nov 2025, 96 months after the start.

Of 466 non-industry observational studies under Pulmonary Disease, Chronic Obstructive, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 64. This study's planned 96 months is above that.

Counting every sponsor, half of 586 studies reached it within 26 months; a quarter within 14 and three quarters within 58.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 18, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
