To higher comprehend the matchmaking amongst the hypertension variables and cognitive handicap, we depending cuatro logistic regression patterns to the total society to best to possess prospective confounding issues (Desk 3). The selection of new modification facts used the guidelines revealed lower than. The correspondence data was performed playing with model step three and you may design 4. From inside the design step 3, the latest blood pressure variables and you can ages was in fact within the logistic regression design as the proceeded details; parameters was basically predicated on the fresh new telecommunications among them continuous parameters old and you may blood pressure level. Inside the model cuatro, new blood circulation pressure parameters and years was basically regarded as categorical details.
No high correlations was basically located between SBP and you may intellectual disability in the models step 1 and you can 2; however, when the communication identity many years by SBP are fixed to possess when you look at the design step three, a prominent correlation was revealed (Dining table 3). Within the model step 3, SBP is actually absolutely correlated having cognitive impairment (Or = step one.130 [95% CI, step one.028–step 1.242] for each 10mmHg, P = 0.011). not, age by the SBP interaction name is adversely correlated having intellectual handicap (Or = 0.989 [95% CI, 0.982–0.997] for every single 10mmHg?12 months, P = 0.006). Thus, the fresh new Or for SBP was step 1.130 for every single 10mmHg to the users regarding mediocre ages (55.five years, inside study) however, reduced to help you 0.989 minutes the early in the day really worth with each most 12 months. Put simply, new Or for SBP for a topic out of a particular decades will be conveyed from the Otherwise = step 1.130?0.989 (age-55.5) per 10mmHg to own 40?age?85. Read More
