Coefficient and associated P values for body mass index, age, sample size, and publication year in meta–regression analysis comparing neutrophil-lymphocyte ratio between gestational diabetes mellitus cases and controls

Covariate	Coefficient (95% CI)	P
BMI GDM	0.004 (–0.086 to 0.094)	.934
BMI controls	0.069 (–0.071 to 0.208)	.334
Age GDM	–0.205 (–0.329 to –0.081)	.001
Age controls	–0.182 (–0.324 to –0.041)	.01
Study size	–0.001 (–0.003 to 0.00)	.09
Publication y	–0.050 (–0.162 to 0.062)	.384

Age in GDM cases and controls was found to significantly affect the NLR (P < .05), whereas other quantitative variables showed no effect.

Abbreviations: BMI, body mass index; GDM, gestational diabetes mellitus; NLR, neutrophil-lymphocyte ratio.
