Kato-Katz ability to detect Ascaris lumbricoides infections shows no pattern between readers or at different times of day. Slides from the baseline time-point are spread along the Y-axis based on the time of day at which they were read. In both panels (a) and (b), samples are shown in blue if the sample was negative for A. lumbricoides by KK, and red if the sample was positive for A. lumbricoides by KK. Samples are shown above the code for the technician who read that slide. The violin plot in panel (c) shows that the core slide-reading period was 2 pm to 5 pm
