Change in the proportion of facilities meeting specific benchmarks for timeliness in the Chicago Breast Cancer Quality Consortium (2006-2013).

a
Number of facilities with data at specified time points.
b
Percentage of facilities meeting the benchmark at each time point.
c
P-values from a Wald test for trend in logistic regression with generalized estimating equations to account for clustering by facility. All P-values >0.20 are suppressed. Data on timely follow-up imaging specific for this benchmark was not collected for CY 2010, therefore no facilities have 5 time points available on this benchmark.
d
Only 4 time points available for analysis of timely follow-up imaging.
