In addition, FENO measurements are simple to perform and were carried out according to current guidelines at constant expiratory flows of 50 mL.s-1 and systematically before spirometry and methacholine challenge.
Again, it's about using common sense here and the reason I am not giving you exact measurements is simple.
The OGTT, though less precise than the clamp measurements, is simpler to perform in epidemiological or intervention studies.
Blood pressure measurements are simpler and more accurate during pharmacological stress echocardiography (dipyridamole or dobutamine) since no movement-related artifacts can occur [ 1].
From the above, it can be easily noticed that applying tape measurement is simple but slow, tedious, and unsafe.
The three measurement issues that we discussed do, however, not apply to phenotypes like height and weight (body mass index), whose actual measurement is simple, but whose considerable heritability also hitherto remains largely "missing" [but see 17].
Hb measurement is simple and affordable, and may be a useful new tool, alone or in association with other metrics, for estimating malaria endemicity and monitoring effectiveness of malaria control programs.
As a risk stratification tool, BNPs measurement is simple, inexpensive, reproducible, non-invasive, and widely available.
The measurement is simple and fast, and requires little or no sample preparation [ 24].
Furthermore, an oscillometric ABI measurement is simple to carry out, has been validated in several studies [ 17- 20], and could easily be integrated in a GP consultation.
