15.5 Patient Closeout Phase
The role of the Coordinating Center in closeout includes:
• Monitoring procedures for patient closeout;
• Assisting in the preparation of papers;
• Developing plans for final data editing and storage;
• Arranging closeout of the Clinics, the CLEK Photography Reading Center,
and the Coordinating Center; and
• Determine final disposition of data files.
15.6 Termination Phase
During the termination phase, study datasets have essentially undergone final

• Completing scheduled data analyses and writing of papers;
• Placing data files and study documents in selected archives; and
• Serving as the CLEK Study communications center.
15.7 Form Design
Forms for the CLEK Study have been designed, field tested and revised during
the planning phase. However, our general policy is pretest, pretest and pretest. Forms

(Section 15.2). The Coordinating Center will prepare and distribute study forms to the
Participating Clinics. The following guidelines will be observed in the generation of
forms:
