Effect on variations in mortality of a unit increase in the value of predictors.

NS = not significant.For every 1 unit increase in the predictor, the predicted count changes by (the coefficient minus 1) times 100%.So, for % of GP registered list on hypertension register in coronary heart disease mortality, for every 1% increase in the register, the predicted count changes by (0.97−1)×100 = −0.03×100 = −3% (a decrease of 3%), and for % of patients with recalled perception of being able to see preferred GP in cancer mortality, for every 1% increase in being able to see preferred GP, the predicted count decreases by (0.997−1)×100 = −0.3% (a decrease of 0.3%).
