| Abstract |
Emphysema has considerable variability in its regional distribution. Cranio-caudal emphysema distribution is an important predictor of the response to lung volume reduction. However, there is little consensus regarding how to define upper and lower-lobe predominant emphysema subtypes. Consequently, the clinical and genetic associations with these subtypes are poorly characterized. We sought to identify subgroups characterized by upper or lower lobe emphysema predominance and comparable amounts of total emphysema by analyzing data from 9,210 non-alpha-1 antitrypsin deficient smokers in the COPDGene cohort. CT densitometric emphysema was measured in each lung lobe. Random forest clustering was applied to lobar emphysema variables after regressing out the effects of total emphysema. Clusters were tested for association with clinical and imaging outcomes at baseline and at 5-year follow-up. Their associations with genetic variants were also compared. Three clusters were identified - minimal emphysema (n=1,312), upper-lobe predominant emphysema (n=905), and lower-lobe predominant emphysema (n=796). Despite a similar amount of total emphysema, the lower-lobe group had more severe airflow obstruction at baseline and higher rates of metabolic syndrome compared to upper-lobe subjects. The upper-lobe group had greater 5-year progression of emphysema, gas trapping, and dyspnea. Differential associations with known COPD genetic risk variants were noted. Subgroups of smokers defined by upper or lower lobe emphysema predominance exhibit different functional and radiologic disease progression rates and the upper-lobe predominant subtype has evidence of association to known COPD genetic risk variants. These subgroups may be useful in the development of personalized treatments for COPD. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 April 2022.
All research outputs
#15,173,117
of 25,382,440 outputs
Outputs from CHEST
#9,785
of 13,212 outputs
Outputs of similar age
#169,727
of 325,640 outputs
Outputs of similar age from CHEST
#145
of 240 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 13,212 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.1. This one is in the 24th percentile – i.e., 24% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 325,640 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 46th percentile – i.e., 46% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 240 others from the same source and published within six weeks on either side of this one. This one is in the 37th percentile – i.e., 37% of its contemporaries scored the same or lower than it.
