For each medicine, the availability is calculated as the percentage (%) of medicine outlets in which the medicine was found on the day of data collection. Price results are reported as median prices in the local currency and also as median price ratios (MPRs). The median price ratio compares local prices with a set of international reference prices (IRPs) reported by the US-based Management Sciences for Health (MSH), and is an expression of how much greater (or lower) the median local medicine price is than the international reference price. A MPR of 2, for example, means that the local medicine price is twice.
