However, industry classifications such as the International Standard Industry Classification do not have a direct concordance to the Harmonized System.
In patients with RA M. fermentans was detected by culture in 13/87 blood samples and in 13/87 by direct PCR, however, there was only concordance between culture and direct PCR in six samples, so M. fermentans was detected in 20/87(23%) of the blood samples from patients with RA by either culture or PCR.
Both the TaqMan and AS-PCR methods had similar negative predictive values (98.9% for AS-PCR and 99.4% for TaqMan method), the TaqMan method had a higher Kappa value (K = 0.963) than the AS-PCR method (K = 0.803), indicating a higher concordance between direct DNA sequence data and results from the TaqMan method.
The sequencing also confirmed the genotyping accuracy of rs760477 (100% concordance between direct sequencing and Sequenom genotyping).
Although having a clear intention is important, some of the studies using MMIC do not provide direct evidence of increased concordance between patients' goals and treatment choices.
Although most prior studies [ 42, 43] have found moderate-to-high concordance between direct and concentrated smear, one earlier study [ 44] – also performed using high-speed centrifugation in an African reference lab – found results similar to those presented here (sensitivity of 43% for direct smear, 44% for concentrated smear, and 55% for direct plus concentrated smear).
In this study, the concordance between the direct and indirect measurements for facial and cranial indices was poor, regardless of age, gender and socioeconomic stratum (Kappa index: 0.189 and 0.388, respectively).
In some cases, it has been possible to pinpoint morphological traits developed as a consequence of co-evolution, including direct or inverse concordances between characters (Thompson, 1994).
Among studies comparing HH compliance measured by AEMS with direct observation (6), 2 evaluated the concordance between methods (95%and64%4%).
Respect to the identification of M. fermentans in patients with RA, there was only concordance between culture and direct PCR in 6 patients, so we identified M. fermentans in 20/87 (23%) patients with RA (Additional file 2).
