These interaction term coefficients, when added to the regression coefficient of the instructional variables in the medium-achievement group, provide us with the regression coefficient of the instructional variable in the low- and high-achievement groups.
24 This estimates an "overdispersion" term that, when added to the sampling variance of each NHS trust, would inflate the funnel limits to fit the observed distribution of caesarean section rates.
More recently, this regimen has been demonstrated to improve long-term survival when added to surgery for operable disease (Cunningham et al, 2005).
Doxorubicin had a significant impact on the response rate and on the long-term overall survival (OS) when added to first-line chemotherapy with cisplatin (The Ovarian Cancer meta-analysis project, 1991; Fanning et al, 1992; A'Hern and Gore, 1995).
The standard error and 99.9% CIs for the parameter relating to the number of general practice consultations were derived from the simple linear regression with financial year coded as a continuous variable; a quadratic term was not statistically significant when added to the regression equation to explore nonlinearity (P = 0.18).
To compare the benefits of a short-term occupational therapy intervention (OTI) when added to the conventional treatment model (CTM) in the functional recovery of patients admitted to an acute geriatric unit (AGU).
Results show that significant improvements in both policy aims can be achieved through expanding existing storage capacity to capture up to 150percentt of long-term average annual water supplies when added capacity is combined with either a proportional sharing of water shortages or unrestricted water trading.
Cox proportional hazards regression was performed after validating the proportionality assumption, i.e., the lack of a significant effect of the interaction term between each covariate and time, when added into regression models.
Find a factor pair with a sum equal to b. Look through the factor pairs and determine which set will produce the b term the middle term and the coefficient of x —when added together.
When added to the models, the age-by-Aβ interaction term was not significant in either case.
