7.5 Results of Univariate OLS regressions<br />
The following table shows the results of the univariate Ordinary Least Square regressions. The only statistically <br />
significant conclusion (at 10% level of statistical significance) that can be drawn from the table below is that the <br />
number of FTEs /1,000 cores is smaller the larger the site. Stata 12 was used to run the statistics. <br />
