The Effect of Reliability and Accuracy on Monitoring and Classification Sample Clauses

The Effect of Reliability and Accuracy on Monitoring and Classification. We showed that 3D imaging produced reliable measurements; we also need to consider how this reliability would affect the quality of anthropometric data outside of a research setting. Most large-scale surveys do not take repeated measurements and so cannot be analyzed for reliability, but reliability is directly related to z-score SD. Reliability is a metric of random error, and as random error increases z-score SD increases. If z-score SD is too high, there may be overdispersion, which can cause overestimation of prevalence below or above z-score cutoffs. High quality surveys have z-score SD between 0.9-1.1 (37, 38); in this study 3D imaging z-score SD was within 0.9-1.1 for all measures. An evaluation of the quality of 52 DHS found that 1 out of 52 had HAZ SD between 0.9- 1.1, and 30 out of 52 had HAZ SD above 1.5 (17). A SD of 1.5 can lead to overestimation of prevalence. A recent study found that DHS and MICS carried out in Western and Central Africa from 1990-2012 may have overestimated the prevalence of stunting (HAZ <-2 SD) by ~10 percentage points on average (38). Overdispersion from poor quality anthropometry can also result in overestimation of overweight and obesity. Poor quality anthropometric data is common in large-scale surveys, and quality is variable between countries and between surveys in the same country; making it difficult to meaningfully compare countries or analyze trends over time. The reliability of 3D imaging and manual anthropometry in BINA was good enough to make meaningful comparisons between countries and over time. Our reliability findings also indicate that 3D imaging can be used for growth monitoring. Considering a well check schedule of visits at 1, 2, 4, 6, 9, 12, 15, 18 and 24 months; the differences in stature between visits is 3.2-5.5 cm according to the 2006 WHO CGS median. The inter-observer TEM for repeated-scan indicates that repeated measurements from 3D imaging can be within 1.5 cm 99.9% of the time — 3D imaging random error would not cause overlapping estimates in growth monitoring. We measured accuracy with average bias, a metric of systematic bias. In the MGRS average bias was considered acceptable if it was within ±2.8 times the expert intra- observer TEM (27); based on MGRS criteria 3D imaging accuracy was acceptable for all measures in our study. However, our findings indicate that the criteria used to assess average bias for the 2006 WHO CGS may be too lenient for the purposes of our study. For head circum...
