Using the more conservative negative binomial approach (also robust to overdispersion) results were consistent: CALS remained significantly associated with the number of medications (IRR = 1.26; 95% CI [1.13–1.40]; p-value < 0.001) and showed a trend-level association with total alerts (IRR = 1.06; 95% CI [0.999–1.124]; p-value = 0.053).
