This is a figure which requires confirmation, and is one that is likely to vary in different parts of the world. We have accordingly carried out a systematic clinical and biochemical screening of the cases of mental subnormality (IQ lower than 70) attending the out-patient department of the Mental Hospital, Bangalore. A total of 729 patients (439 males and 290 females) were available for this study.<\/jats:p>","DOI":"10.1192\/bjp.118.546.505","type":"journal-article","created":{"date-parts":[[2008,8,12]],"date-time":"2008-08-12T22:35:43Z","timestamp":1218580543000},"page":"505-507","source":"Crossref","is-referenced-by-count":4,"title":["A Clinical and Biochemical Survey of 729 Gases of Mental Subnormality"],"prefix":"10.1192","volume":"118","author":[{"given":"B.
