Revised conclusion paragraph

The aim of this paper has been to examine the health care costs of non-profit and for-profit hospitals in the United States. In particular I have surveyed the effects of decreasing co-payments under each system. As the tables show, in non-profit hospitals, costs increased by 4.8%, whereas in for-profit hospitals, increases were almost six times as high, amounting to an average of 24.7%. Taking these appalling numbers as statistical evidence for an implicit discrepancy regarding patient treatment, I have suggested a link between reduced co-payments and an increased proportion of tests ordered by physicians who work in for-profit hospitals. Several indications have led me to formulate this hypothesis, including a vast number of cross-referenced studies that have already been conducted in this area, according to which cost containment may prove very difficult in a free market economy. However, while the findings presented in the present paper seem to support the abovementioned claim, they are still to be considered somewhat provisional at this stage. Important factors such as patient income, age, and level of satisfaction with the health-care provider have not been taken into consideration yet. Further research is thus strongly needed in order to arrive at more precise data that may allow for a profound evaluation of these crucial findings.
