"main effect estimate" is a correct phrase that can be used in written English.
It is typically used in research or statistical analysis to refer to the estimate or measurement of the main or primary factor or variable being studied. Example: The main effect estimate for the impact of exercise on overall health was found to be statistically significant, with a p-value of less than 0.05.
In addition, we performed a meta-analysis using the main effect estimate from each of the 26 epidemiological studies.
The direct effects of both measures of SEP were modelled in logistic regression; odds ratio was the main effect estimate.
Covariates were selected in the regression procedure if they changed the R and/or main effect estimate by > 10%.
The direct effects of both measures of SEP on binary outcomes was modelled in logistic regression and odds ratio was the main effect estimate.
Accordingly, the main effect estimate for any locus was taken to be the difference between the effect of the Dd2 genotype and the HB3 genotype.
Covariates were retained in the models if the main effect estimate of plasma or blood lead on breast milk lead changed by > 10% or if it increased the model coefficient of determination (R) by > 10%.
Main effect estimates were not appreciably altered by inclusion or exclusion of a range of covariates or adjustment for baseline CIMT, and adjusted coefficients were without exception slightly larger than the crude associations.
Among regions, main effect estimates were significant for Gipuzkoa only [β (95% CI) = –5.15 (–8.04, –2.27) and –5.49 (–9.21.761.76), respectively, for a doubling of each compound].
Smoking and illicit drug use were not included in the model because few women reported these behaviors and they did not influence main effect estimates.
The precision of the main effect estimates was similar for the models adjusted for CDS-ID only and age only (95% CI width 4.87 and 4.71, respectively).
We identified 22 SNPs in 11 genes with ptrend < 0.05 for main effects on prostate cancer [ Table 2; for main effect estimates for all other BER SNPs, see Supplemental Material, Table 2 (http://dx.doi.org/10.1289/ehp.1103454)].
