Introduction: Urbanization has challenged many humanitarian practices given the complexity of cities. Urban humanitarian crises have similarly made identifying vulnerable populations difficult. As humanitarians respond to cities with chronic deficiencies in basic needs stressed by a crisis, identifying and prioritizing the most in need populations with finite resources is critical.

Methods: The full systematic review applied standard systematic review methodology that was described in detail, peer-reviewed, and published before the research was conducted.

Results: While the science of humanitarian practice is still developing, a systematic review of targeting vulnerable populations in urban humanitarian crises shed some light on the evidence base to guide policy and practice. This systematic review, referenced and available online, led to further findings that did not meet the pre-defined inclusion and exclusion criteria for evidence set out in the full review but that the authors, in their expert opinion, believe provide valuable insight nonetheless given their recurrence.

Discussion: These additional findings that did not meet criteria for evidence and formal inclusion in the full manuscript, but deemed valuable by the subject expert authors, are discussed in this commentary
