Table 1 Variables and parameter descriptions
From: Incidence and admission rates for severe malaria and their impact on mortality in Africa
Name | Description |
|---|---|
Variables | |
U | Incidence rate of uncomplicated clinical malaria (per 100,000 person per year) |
S | Incidence rate of severe clinical malaria (per 100,000 person per year) |
C | Incidence rate of total clinical malaria (C = U + S) (per 100,000 person per year) |
D | Incidence rate of malaria mortalitya (per 100,000 person per year) |
μ | Proportion of severe cases treated as in-patients (−) |
r | Ratio of severe to total clinical cases for in-patients (−) |
Q R | Case fatality rate (−) Estimated public health impact (as malaria mortality) averted with maximal improvement to admittance of severe disease patient (μ = 1) (per 100,000 person per year) |
\(\rho\) | The overall ratio of the number of deaths per year in WMR (\(\hat{D}_{t}\)) [allowing for the national population (N)], to that predicted by OpenMalaria (\(\bar{D}_{{t,\mu ,\bar{\varphi }_{1} }}\)) |
Subscripts | |
h | Indicates in-patient event |
c | Indicates event in community |
t | Indicates total events |
PB | Indicates prediction-biased estimate |
DA | Indicates deaths-adjusted estimate |
\(\mu_{0}\) | Indicates estimate used in OpenMalaria analysis for the proportion of severe cases treated as in-patients (usually \(\mu_{0}\) = 0.48) |
\(\overline{\varphi }_{x}\) | Indicates estimate calculated with the odds ratio of value \(\overline{\varphi }_{x}\) |
Accents | |
\(\bar{}\) | Indicates estimation from OpenMalaria simulations |
\(\hat{}\) | Indicates estimation from WMR |
