*Based on 1033.4 million population for India and 19.4 million for Australia in 2001 [1]

†Based on the gross domestic product adjusted for purchasing power parity (GDP-PPP) of US$ 2930 billion for India and US$ 491.8 billion for Australia in 2001 [1]

‡Based on multiplying the number of papers and their total impact factor for the April-June 2002 quarter by four to obtain the estimate for the year 2002

The total of the number and impact factor for basic, clinical and public health papers does not add up to that for the health papers, as 6 "other" papers (with total impact factor 6.012) that could not be classified as basic, clinical or public health (Table 1) are not included in this table
