Slot: retention_incentives
Where the sources describe it, how the incentive structure was designed to keep participants enrolled across the study — escalating amounts, completion bonuses, payments tied to later visits or to returning after a gap.
Distinct from compensation_type and compensation_amount, which record what was provided. State this only where a source describes the structure. An escalating payment schedule is not by itself evidence that retention was its purpose; report the schedule under the compensation slots and leave this absent.
⚠️ "Retention" here means keeping participants enrolled, never keeping data. How long the data is kept belongs in retention_limit, which is a different slot about a different subject. The word is treacherous in this corpus: across all five project bundles nearly every occurrence of "retention" is about data or specimen retention — "limits on the retention of the data", "bioSpecRetention", "records retention requirements" — and none so far describes an incentive structure. An empty slot is the correct outcome for those sources.
