Estimated pneumonia-free probability according to the use of medications during post-stroke follow-up period.

Abstract

Each plot illustrates estimated pneumonia-free survival curves according to the use of PPI (A), H2RA (B), and mucoprotective agents (C) during the followed-up period after stroke. Mucoprotective agents include rebamipide, teprenone, irsogladine, ecabet, polaprezinc, sofalcone, sucralfate, and misoprostol. Abbreviations: H2RA, H2-receptor antagonist; PPI, proton-pump inhibitor.</p
