Significance was tested by a t-test followed by a false discovery rate correction in the Benjamini-Hochberg procedure (FDR cut off 0.02).
The procedure was to cut off the highest, fully-open trifoliate leaf from 20 plants in each rep.
Hematocrit levels were assessed by microhematocrit procedure (cut-off points: males, 38 52%, females, 36 51%).
However, our procedure cut-off the genes if their fold change values were just below the upper 2.5 percentile.
P-values from Fisher's exact test were adjusted for multiple testing (False Discovery Rate) using the Benjamini-Hochberg step-up procedure; cut-off was set at 0.05.
Hemoglobin levels were measured by cyanomethahemoglobin reaction procedure (cut-off points: in males, 12.17 17.26 g/dL, and in females, 11.48 16.25 g/dL).
This observation suggests that prevalence numbers obtained by different case definitions should be controlled according to diagnostic procedure, cut-off points and reasons for exclusions before concluding on differences.
Although the responses to the two aforementioned questions were near to the usual significance level, those were not considered significant after their alpha level was corrected by the Bonferroni's procedure (cut-off for 15 comparisons: 0.003) [ 21, 22].
Efforts to control messaging during riots are likely to focus on social media rather than mobile phone companies, because there is no simple procedure for police to cut off individual phones at short notice.
Thus, once potential QTLs were detected by interval mapping analysis, markers with higher LOD scores were selected as cofactors and tested using the automatic cofactor selection procedure (default P value cut off for elimination of a cofactor set of 0.02).
The questionnaire was designed to obtain information about the screening procedure, diagnostic criteria and cut off values used; as well as get an understanding of the challenges and barriers in implementing the guidelines in the local context in terms of ethnic and cultural issues, resources and capacity.
