Figure 5From: Dried blood spots as a source of anti-malarial antibodies for epidemiological studiesArrhenius plot of rates of loss of antibodies. Rate of loss of antibody titre at each temperature (k days-1, the fitted first order rate constant) versus the reciprocal of the absolute temperature in °K (1/T). • measured points; + extrapolated values for 10°C, 4°C and -20°C;. The weighted best fit straight line is shown together with the 95% confidence limits.Back to article page
