Measurements are simple and rapid (~ 5 min), and the technique is applicable to other compounds provided appropriate antibodies are used.
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.
The OGTT, though less precise than the clamp measurements, is simpler to perform in epidemiological or intervention studies.
Measurements were rounded to the nearest 1/10th of a mm and were taken by the first author (N.A). to eliminate the inter-rater reliability and given the accuracy of the digital caliper to 0.0005/0.25 mm and the fact that the measurements were simple linear distances would decrease the chance of intra-rater errors.
Again, it's about using common sense here and the reason I am not giving you exact measurements is simple.
With this approach, measurement is simpler, but the overall assessment should also consider the incidence of external factors, thus resulting in a simpler but less reliable analysis.
Also, volume measurement is simpler during pharmacological stress echocardiography, with the patient lying down on the left side, for an optimal visualization of the cardiac structures, especially during dipyridamole stress echo, due to the low heart rate values at peak stress [ 34].
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.
