Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
The study was opened on Nov 21, 2003, and closed on Sept 12, 2008, with final accrual of 545 patients.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Patients received induction rituximab IV once a week for 4 weeks. Patients were re-evaluated 9 weeks after the completion of induction rituximab. Patients with a partial or complete response to induction rituximab were randomized to one of the two treatment arms, stratified on histology (follicular vs other), age, and time from diagnosis.

Reporting Groups
  Description
Rituximab Retreatment: Follicular Patients Following induction rituximab, patients who were randomized to this arm received rituximab IV once a week for 4 weeks upon disease progression provided time to progression is more than 6 months. Follicular and non-follicular patients were analyzed separately per protocol.
Rituximab Scheduled: Follicular Patients Following induction rituximab, patients who were randomized to this arm received a single dose of rituximab IV once every 13 weeks until disease progression and in the absence of unacceptable toxicity. Follicular and non-follicular patients were analyzed separately per protocol.
Rituximab Retreatment: Non-Follicular Patients Following induction rituximab, patients who were randomized to this arm received rituximab IV once a week for 4 weeks upon disease progression provided time to progression is more than 6 months. Follicular and non-follicular patients were analyzed separately per protocol.
Rituximab Scheduled: Non-Follicular Patients Following induction rituximab, patients who were randomized to this arm received a single dose of rituximab IV once every 13 weeks until disease progression and in the absence of unacceptable toxicity. Follicular and non-follicular patients were analyzed separately per protocol.
Enrolled But Not Randomized Patients who were enrolled in the study but not proceed to randomization. These could include patients with undetermined histology as well as those who did not achieve response (PR or CR) after induction rituximab.

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
As the primary analysis only includes randomized patients, the baseline characteristics were provided among patients who were correctly randomized to one of the two arms for maintenance therapy.
