Table 4.

Association between receipt of cancer-directed treatment and quartiles of predicted DS, by disease site and stage ,

Early Stage NSCLC, %
(n = 20,280)*
Advanced NSCLC, %
(n = 31,341)*
Stage IV ER- Breast Cancer, %
(n = 1,519)*
MDS, %
(n = 6,058)*

Disability Status (DS) Received Surgical Resection Received Chemotherapy within 90 Days of Diagnosis Received Chemotherapy within 6 Months of Diagnosis Received ESAs Any Time Post Diagnosis
Overall, % 62.3 34.3 32.5 64.1
Predicted probability poor DS:  
Q1 (lowest probability poor DS) 77.3 49.1 43.1 73.7
Q2 70.7 40.0 34.7 71.0
Q3 60.2 30.2 33.0 66.7
Q4 (highest probability poor DS) 41.4 18.4 19.3 45.5

Percentages reported (row %) are the proportion who received treatment by DS.

All comparisons were statistically significant at an alpha level of 0.05 (calculated by χ2 test).
