In a recent article in this Journal, Holland et al. correlate TB incidence in the United States since 1952 with time, immigration, and HIV in the late 1980s and early 1990s. 1 The authors also correlate proportional decreases in TB incidence in 2008–2009 with increases in unemployment in 2009–2010 in a separate linear regression in which lagged unemployment explains about 10% of state variance in TB incidence (R2=0.10).
