Inconclusive Evidence (formerly "Insufficient Evidence")

Programs or practices with inconclusive evidence are those that have been reviewed by Study Reviewers, but were not assigned an evidence rating due to limitations of the studies included in the programs' evidence base. Programs are placed on the inconclusive evidence list if the study (or studies) reviewed (1) had significant limitations in the study design or (2) lacked sufficient information about program fidelity so that it was not possible to determine if the program was delivered as designed.

Note that these programs and practices were previously referred to as "insufficient evidence."
