If it turns out we want low bicarbonate levels an the common tests for CO2 measure bicarbonate level then many people on the forum showing results with high bicarbonate actually have a problem, while they have been reassured that it is a good sign.
In its broadest form, evidence-based medicine is the application of the scientific method into healthcare decision-making. Medicine has a long tradition of both basic and clinical research that dates back at least to Avicenna.
When we think about evidence based decision-making in particular, evidence is defined as information or facts that are systematically obtained (i.e., obtained in a manner that is replicable, observable, credible and verifiable) for use in making judgments or decisions (adapted from Rycroft-Malone et al, 2004 & Brownson et al., 2009).
