Sample 10,000-subject cohort, 4542
subjects were chosen
130 male gender patients
along with 20 smoking control
males are enrolled in this
study
CT Scans of Patients who has
COPD and related disorders
were chosen
Sampling Method Random sampling
Lobe by lobe volumetric data
was chosen
Random sampling, in this case
eased the process of selection,
helping the participants of the
study select the right type of
the sample size and it is
important to be noted that a
volumetric data was to be
chosen.
Convenience sampling
Subjects were chosen
who had a
(1) 20 year old history
smoking with related
diagnosis of chronic
obstructive along with
a history of present
illness to 4 weeks (2)
the gold standard
should have been used
3) confirmed with CT
scan previously (4) In
past 4 weeks, no
exacerbations within
COPD
Exclusion criteria
(1) do not have 20
year old history
smoking with
related
diagnosis of
chronic
obstructive
along with a
Snowball sampling
Snowball sampling, in this
case eased the process of
selection, helping the
participants of the study select
the right type of the sample
size and it is important to note
or rather consider very vitally
that the bias presentations
were eliminated from the data
set and analysis as this
sampling method was used.
