> > I have some questions regarding the interpretation of incidence-rate ratio (IRR) from the negative binomial regression. In particular, it is the incidence-rate ratio of interaction terms between the binary variable (dummy) and the continuous variables. > > In my study, the model ...
In the main adjusted model, we observed an incidence rate ratio (IRR) of 2路35 (95% CI 2路12-2路60) for COVID-19 incidence per log unit increase in the mobility ratio (vs baseline) during the previous week. Thus, 10% lower weekly mobility was associated with 8路6% (95% CI 7路...
Estimated smoking exposure response of the incidence rate ratio (IRR) and 95% confidence intervals for specified lag periods (years). IRR is computed using the reference level of 50% smoking prevalence (i.e. the mean across all lags and countries). Accordingly, the IRR = 1 at smoking...
Incidence rates in CFAS I and II for six 5 year age groups are shown in Fig. 2. The reduction in incidence is calculated as an incidence rate ratio (IRR) 0.8 (95% CI: 0.6–1.0, P=0.08, Poisson regression, N=10,444). Table 1 Incidence rates per 1,000 person years by age ...
The dementia incidence rate ratio (IRR) following any infection was 1.49 (95% CI, 1.47-1.52) and increased along with increasing numbers of infections in a dose-dependent manner. Dementia rates were increased for all infection sites in the short term, but not always in the long term. The ...

Results The overall incidence rate of all-cause dementia was 18.2% (95% confidence interval [CI], 15.3-21.5) per year and was similar for men and women (risk ratio, 0.94; 95% CI, 0.65-1.37). Rates increased exponentially with age from 12.7% per year in the 90-94-year age group, ...
While 55% of EM cases were observed among females, more males reported extracutaneous manifestations: 56% of NB cases (Incidence rate ratio (IRR) 1.3, 95% CI 1.2–1.4) and 53% of LA cases (IRR 1.2, 95% CI 1.1–1.3) affected males. ...
rate ratio varied across datasets: 1.86 (Medicare, 85+ years), 2.18 (Ontario 85+ years), 2.51 (REP, 75-84 years) 2.58 (KPNC, 75–84 years). When individuals below the age of 65 were included, a higher incidence of PD among males remained; however, the male: female sex ratio ...
