Correlation coefficient r = -018 (insignificant) thus it appears that in developed countries with the highest levels of health care spending, le goes down somewhat as hcs increases however, if we look at very poor or developing countries, where the hcs is very low today (and even primary health care may be inadequate), we may find that le.
