The clinical criteria used to score LUS videos that have been evaluated by the algorithm beforehand. The labelling system determines a certain confidence of an experienced sonographer to identify the overall rating of a video based on the corresponding consolidation/collapse imaging pattern per frame using anatomical markers, image quality, and other possible obstructions for appropriate identification.

	Y	Y*	N
Obstructions to identification	Little to no ambiguity or obstructions to view	Possible causes: - artefacts overlappin - poor ultrasound probe placement
Consolidation/collapse identified	Conclusive frames	Conclusive frames inconclusive frames	Inconclusive frames
Anatomical landmarks/scanning regions identified	Conclusive frames	Conclusive frames inconclusive frames	Inconclusive frames
Image quality	Good to high	Not optimal to normal	Not optimal/poor
