First paragraph (this article has no abstract)

Wunsch and colleagues analyzed the effect of window rooms on critically ill patients admitted to the ICU with subarachnoid hemorrhage, and concluded that the presence of a window in an ICU room did not improve their outcomes [1]. We commend the attempt to associate natural light with improved outcomes for hospitalized patients, but we have some concern as regards the data analysis and interpretation.
