For those cases, a specific scoring procedure is applied in a fourth step to assess the strength of the NMDR relationships. This scoring procedure is derived from the criteria proposed by Calabrese and Baldwin [12] for hormesis (a specific type of NMDR profile). Briefly, the procedure developed by Calabrese and Baldwin is a numeric scoring assignment value including the number of tested dose levels, the magnitude of the response associated with each dose compared to the basal level, the significance of the response at each dose, and the presence of other studies confirming these data (Table 1). These criteria were used because we considered PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/26866270 these parameters important and sufficient to define the non-monotonic nature of a dose-response relationship and estimate the plausibility of a presumed NMDR relationship (Table 2). The criteria used here are the criteria suggested by Calabrese and Baldwin adjusted for a use in this application. Each score was assessed individually withoutTable 1 Summary of criteria of analysis with assigned point values used in the evaluation of statistical plausibility of an NMDR relationshipNumber of doses below ZEP (excluding the control) 1 2 3 4 5 Experimental determination of ZEP Yes No Number of doses statistically different from control 1 2 3 4 Reproducibility of the dose-response relationship Yes No Magnitude of response (percentage control value) Inverted-U curve 100 , 125 >125 , 150 >150 , 200 >200 , 400 >400aTable 2 Summary of total score for plausibility of an NMDR relationshipTotal scorea 1? >2? >8?2 >12?6 >16?0 >aPlausibility of an NMDR relationship No ow Low Low oderate Moderate Moderate igh HighThese scores were extracted from Calabrese and Blain (2011) [14].Score A 1 2 3 4 5 Score B 1 0 Score C 2 4 8 16 Score D 3 0 Score EaU curve 97 , 92 <92 , 84 <84 , 68 <68 , 5 <5 0,5 1 2 3considering whether NMDR relationships were reported or not in the same study. A score of "moderate," "moderate igh" or "high" was considered in this work as indicative of a sufficient strength. The fifth and last step of the assessment is to determine whether the previously suspected NMDR relationship is also supported by biological plausibility. So an additional assessment of the literature is made to check whether additional information would support the biological plausibility and then increase the confidence PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/28380356 in the reported NMDR.
