Liquid or soft-gel levothyroxine vs tablet levothyroxine in athyreotic adults after total thyroidectomy: Systematic review and meta-analysis

BACKGROUND Achieving stable thyroid hormone replacement after total thyroidectomy is challenging owing to the variability in levothyroxine (LT4) absorption. Newer liquid and soft-gel formulations may offer improved bioavailability compared to conventional tablets, but their benefits in thyroidectomized patients remain uncertain. AIM To compare the effectiveness of liquid and soft-gel LT4 with tablet LT4 in athyreotic adults following total thyroidectomy. METHODS A systematic review and meta-anal
