Table 1 Key features of the full parasitaemia profile
| Â | Key feature | Definition |
|---|---|---|
(i) | The initial slope | The slope of a linear regression line through the log densities from the first positive slide to the first local maximum (per day) |
(ii) | Number of local maximums | A measurement was a maximum if its density was higher than the densities at times t: (t−6), (t−4), (t−2), (t + 6), (t + 4), (t + 2) (no units) |
(iii) | Density at the first maximum | Density at the first maximum (log Parasitized Red Blood Cells (PRBC) per microlitre) |
(iv) | The slope of local maximums | The slope of a linear regression line through the log densities of the local maxima (per day) |
(v) | The geometric mean | The geometric mean of the intervals between consecutive local maximums (days) |
(vi) | The standard deviation | The standard deviation of the logs of the intervals between consecutive local maximums (no units) |
(vii) | The proportion of positive in the first interval | The proportion of measurements higher than zero in the first half of the interval between the first and last positive day (no units) |
(viii) | The proportion of positive in the second interval | The proportion of measurements higher than zero in the second half of the interval between the first and last positive day (no units) |
(ix) | The last positive day | The last days that the patient had a parasitaemia higher than 0 (days) |
