Forest plots of the ORs for local and systemic reactogenicity (pregnant women vs nonpregnant women).

(a) OR for muscle pain in pregnant women after the first dose (OR = 0.45, 95% CI: 0.22-0.93, P = 0.03); (b) Muscle pain after receipt of the second dose of a COVID-19 vaccine (OR comparing pregnant to nonpregnant women 1.28, 95% CI: 0.73-2.23, P = 0.39); (c) Fatigue in pregnant women compared with nonpregnant women (first dose: OR = 0.90, 95% CI: 0.63-1.28, P = 0.56); (d) Fatigue in pregnant women compared with nonpregnant women (second dose: OR = 0.89, 95% CI: 0.65-1.22, P = 0.48); (e) Risk of developing a fever in pregnant women compared with nonpregnant women (random effect models, first dose: OR = 1.02, 95% CI: 0.12-8.61, P = 0.98); (f) Risk of developing a fever in pregnant women compared with nonpregnant women (random effect models, second dose: OR = 0.65, 95% CI: 0.42-1.01, P = 0.05).

CI, confidence interval; OR, odds ratio.
