| 135 | Because the parameter is undeclared, comparison between published studies requires care. Studies differ in whether the needle is included, whether the measurement is made with the plunger merely bottomed or forced, and whether back-pressure representative of tissue is applied. Values quoted without those details are not strictly comparable, and a difference between two published figures for the same device class is at least as likely to reflect protocol as product.{{r|bobashev2010}} | 135 | Because the parameter is undeclared, comparison between published studies requires care.

| + | 137 | Community-collated measurements of devices commonly used with reconstituted research peptides exist but are self-reported, use domestic balances of unstated calibration status, and do not control for the protocol variables above. They are consistent with the published device classes in magnitude and are not adequate to support finer distinctions.{{r|ppdeadspace}} | |
