[…] in the model. family-based studies accounted for relatedness using mixed effect models. details on the study-specific methods are reported in ., all gwas files underwent quality control using the gwatoolbox package. gwas meta-analyses for egfrcrea and egfrcys were performed using the software metal assuming fixed effects across studies and using inverse-variance weighting, excluding variants […]

[…] quality control prior to meta-analysis. checking of file formatting, data plausibility, and distributions of test statistics and quality measurements was facilitated by the gwasqc function of the gwatoolbox package v1.0.0 in r []. prior to the meta-analysis, variants with low minor allele frequency (<1%) and poor imputation quality (r2< 0.4) were removed., meta-analysis was performed […]

[…] for a total sample size of 117,165, including 12,385 ckd cases. gwas of egfrcys were comprised by 16 studies for a total sample size of 32,834. all gwas files underwent quality control using the gwatoolbox package in r, before including them into the meta-analysis. genome-wide meta-analysis was performed with the software metal, assuming fixed effects and using inverse-variance weighting.

[…] the regression for ever-smoking status and used appropriate tests for association in related individuals, as described in the ., quality-control checks on the stage-1 data were undertaken using gwatoolbox and r version 3.0.2 (see urls). all meta-analysis steps were undertaken using inverse variance-weighted fixed-effects meta-analysis. effect estimates were flipped across studies […]

[…] as the dependent variable that was regressed on imputed allelic dosages for each snp in the gwas., before the meta-analyses, all study-specific gwas summary files underwent quality control using the gwatoolbox (). genomic-control (gc) () correction was applied when the gc factor was >1. inverse variance weighted fixed-effects meta-analyses were conducted using metal (). the i2 statistic […]
