Bland-Altman plot of the agreement between DBS versus plasma viral load.

<p>The horizontal dotted line represents the mean difference of 0.077 log₁₀. The grey area represents ±1.96 standard deviations. The vertical dotted line represents the 3 log₁₀ cut-off for detectable viral load.</p

Correlation between measurement of DBS versus plasma viral load.

<p>The vertical dotted line represents the cut-off for WHO guidelines relating to regimen switching of 3 log₁₀. Where the DBS sample load was above 1000 copies, a line was fitted with ordinary-least-squares regression to the log of the viral load results from the DBS and plasma samples. The resulting line was: log₁₀(Load_{<i>Plasma</i>}) = 0.29 + 1.01 * log₁₀(Load_<i>DBS</i>).</p

<p>The total column height represents the overall percentage of births that were reported to have been unintended (unwanted or mistimed); the white portion represents the percent of women who were not using contraception prior to the pregnancy (unmet need) and the black portion represents the percent of women who reported using contraception before pregnancy (presumed contraceptive failures)^a. <i>a. Percentages of unmet need and contraception use may not sum to column totals due to rounding.</i></p
