Detailed Instructions: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Q: Abstract: Our results suggest that ethylene oxide retention after sterilization is increased in cuprammonium cellulose plate dialyzers containing potting compound. In contrast, cuprammonium cellulose plate dialyzers without potting compound were characterized by a rapid disappearance of retained ethylene oxide after sterilization. Whether these findings explain the low incidence of SARD with cuprammonium cellulose plate dialyzers that do not contain potting material is a matter for continued study and experimentation.
Which is the apt title for the abstract? option1: Extractable ethylene oxide from cuprammonium cellulose plate dialyzers: importance of potting compound. option2: Facial involvement in pruritic urticarial papules and plaques of pregnancy [letter]
A:
Extractable ethylene oxide from cuprammonium cellulose plate dialyzers: importance of potting compound.
