An example of oxygen-related questions.

Several of the experts implied an apparent discrepancy in the perceived importance of oxygen delivery between the donors for health research, technical experts, and the implementers and programme leaders. The final ranks for the nine research questions related to oxygen research spread from 11th to 144th (among 158 suggested ideas). The ratio between highest and lowest scores varied widely across criteria: answerability (1.24), effectiveness (2.47), deliverability (2.05), impact of disease burden (4.56), impact on equity (1.39), and overall RPS (1.79). This example shows how a focus on addressing e.g., “oxygen research for pneumonia” would be too broad, and that prioritisation should be made between more specific research ideas to be meaningful.
