Low molecular weight heparins and hypoaldosteronism.

Abstract

ADDENDUM-In view of the long term benefit appar- ently due to chiropractic we initiated a three year follow up, sending multiple reminders to those initially not responding.By mid April 1990-beyond the closing date for the earlier results -data were available for 113 patients, representing a 79% response.At three years the mean fall in Oswestry score for those treated by chiropractic was 9-6% points more than for those treated in hospital (p=0-01).The fall was greater (13 8% p=0 0003) among those presenting with current episodes of more than a month's duration than for those presenting with episodes of less than a month (5 3%, NS).Among those with a previous history of back pain, the improvement in Oswestry score at three years was 9-7% points greater in patients treated by chiropractic than those treated in hospital (p=002).A similar difference between the two forms of treatment (9-4%) was found among those with no previous history of back pain, but numbers in this group were smaller and the difference was not significant. 1
