<p><strong>Remember that you should filter your data to let it contain only first isolates!</strong> This is needed to exclude duplicates and to reduce selection bias. Use <code><a href="first_isolate.html">first_isolate()</a></code> to determine them in your data set with one of the four available algorithms.</p>
<p>The function <code>resistance()</code> is equal to the function <code>proportion_R()</code>. The function <code>susceptibility()</code> is equal to the function <code>proportion_SI()</code>. Since AMR v3.0, <code>proportion_SI()</code> and <code>proportion_I()</code> include dose-dependent susceptibility ('SDD').</p>
<p>Use <code>sir_confidence_interval()</code> to calculate the confidence interval, which relies on <code><a href="https://rdrr.io/r/stats/binom.test.html" class="external-link">binom.test()</a></code>, i.e., the Clopper-Pearson method. This function returns a vector of length 2 at default for antimicrobial <em>resistance</em>. Change the <code>side</code> argument to "left"/"min" or "right"/"max" to return a single value, and change the <code>ab_result</code> argument to e.g. <code>c("S", "I")</code> to test for antimicrobial <em>susceptibility</em>, see Examples.</p>
<p>These functions are not meant to count isolates, but to calculate the proportion of resistance/susceptibility. Use the <code><a href="count.html">count_*()</a></code> functions to count isolates. The function <code>susceptibility()</code> is essentially equal to <code><a href="count.html">count_susceptible()</a></code><code>/</code><code><a href="count.html">count_all()</a></code>. <em>Low counts can influence the outcome - the <code>proportion_*()</code> functions may camouflage this, since they only return the proportion (albeit dependent on the <code>minimum</code> argument).</em></p>
<p>The function <code>proportion_df()</code> takes any variable from <code>data</code> that has an <code><a href="as.sir.html">sir</a></code> class (created with <code><a href="as.sir.html">as.sir()</a></code>) and calculates the proportions S, I, and R. It also supports grouped variables. The function <code>sir_df()</code> works exactly like <code>proportion_df()</code>, but adds the number of isolates.</p>

<p>In 2019, the European Committee on Antimicrobial Susceptibility Testing (EUCAST) has decided to change the definitions of susceptibility testing categories S, I, and R as shown below (<a href="https://www.eucast.org/newsiandr" class="external-link">https://www.eucast.org/newsiandr</a>):</p><ul><li><p><strong>S - Susceptible, standard dosing regimen</strong><br>
A microorganism is categorised as "Susceptible, standard dosing regimen", when there is a high likelihood of therapeutic success using a standard dosing regimen of the agent.</p></li>
<li><p><strong>I - Susceptible, increased exposure</strong> <em><br>
A microorganism is categorised as "Susceptible, Increased exposure</em>" when there is a high likelihood of therapeutic success because exposure to the agent is increased by adjusting the dosing regimen or by its concentration at the site of infection.</p></li>
<li><p><strong>R = Resistant</strong><br>
A microorganism is categorised as "Resistant" when there is a high likelihood of therapeutic failure even when there is increased exposure.</p><ul><li><p><em>Exposure</em> is a function of how the mode of administration, dose, dosing interval, infusion time, as well as distribution and excretion of the antimicrobial agent will influence the infecting organism at the site of infection.</p></li>
</ul></li>
</ul><p>This AMR package honours this insight. Use <code>susceptibility()</code> (equal to <code>proportion_SI()</code>) to determine antimicrobial susceptibility and <code><a href="count.html">count_susceptible()</a></code> (equal to <code><a href="count.html">count_SI()</a></code>) to count susceptible isolates.</p>
