TXA: tranexamic acid; CEA: clinician erythema assessment score; VAS: visual analogue scales; CTA: clinician telangiectasia assessment grades; SD: standard deviation; X2: Chi square test; MW: Mann-Whitney test; HS: p-value < 0.001 is considered highly significant. S: p-value < 0.05 is considered significant.
