Drug advertising and prescribing
The Journal of the Royal College of General Practitioners
|September 1, 1978
Abstract:
A study of the amount of drug advertisements received by general practitioners and the amount of the drugs practitioners prescribed showed a strong correlation of 0.80. Analysis suggests that a straight line graphic relationship provides the best fit for the results obtained.FURTHER ANALYSIS OF THE QUANTITY OF ADVERTISING IN RELATION TO THE AMOUNT OF PRESCRIBING REVEALED TWO GROUPS OF DRUGS: those which were relatively more and those which were relatively less often advertised in proportion to the number of prescriptions issued for them.
