Box and whiskers plot of seven groups of sera tested for anti-NIE IgG antibodies.

<p>The plots summarize the results of gold standard <i>Strongyloides</i> samples (n = 54) and six control groups comprised of healthy individuals (n = 7) as well as those with trichinosis (n = 8), filariasis (n = 9), schistosomiasis (n = 9), echinococcosis (n = 6) and amebiasis (n = 8). The lower and upper boxes represent the samples in the second and third quartile respectively while the error bars above and below the box correspond to the 95^th and 5^th percentiles. The horizontal lines separating the boxes represent the median and the diamond denotes the mean. X represents the minimum and maximum values. A significant difference was observed between the gold standard <i>Strongyloides</i> and all control groups (<i>p</i><0.001).
