No monitoring vs frequent monitoring (12 hours or less) of gastric residual volume

Pneumonia · adults receiving EN via nasogastric or gastrostomy tube

It is very uncertain whether no monitoring changes pneumonia (until discontinued or up to 28 days) compared with frequent monitoring (12 hours or less) of gastric residual volume (very low certainty).
