1.  Ambulatory blood pressure in schoolchildren 
Archives of Disease in Childhood  1999;80(6):529-532.
OBJECTIVE—To define the range and variability of ambulatory blood pressure in normal schoolchildren.
DESIGN—Prospective study.
METHODS—Resting blood pressure of 1121 schoolchildren from Newcastle upon Tyne was recorded. An ambulatory blood pressure device, which uses both auscultatory (Korotkoff) and oscillometric methods of blood pressure measurement, was then put in place for 24hours.
RESULTS—The day was divided into three time periods: school, home, and night time. Normal centiles for blood pressure for each of these time periods were obtained and many daytime readings were outside reported normal resting levels. The normal variation of blood pressure was quantified by comparing each of these time periods with the resting readings. Resting systolic blood pressure did not predict 24 hour mean systolic blood pressure.
CONCLUSIONS—The availability of normal ambulatory blood pressure data on the level and variation of blood pressure in children may facilitate the early identification of hypertension in this age group.

2.  The correlates of research success. 
A survey was carried out of the undergraduate backgrounds and research achievements of 885 (94.1%) of all 940 medically qualified professors and readers in medical faculties in the United Kingdom. A total of 217 (24.5%) of the graduates in these senior academic positions had graduated from Oxford or Cambridge and 137 (15.5%) had an intercalated BSc. The corresponding figures for a control group matched for sex and date of graduation were 118 (13.3%) for Oxford and Cambridge (academic to control odds ratio 2.11:1) and 34 (3.8%) for the BSc (odds ratio 4.58:1). Those with an intercalated BSc in the clinical specialties raised substantially more research grants from the Medical Research Council than their peers from Oxford and Cambridge or those without a BSc. The Oxford and Cambridge group raised more grants in the non-clinical specialties. Bibliometric analysis was carried out on the United Kingdom graduates within the broad specialty of medicine (n = 218) matched for date of graduation. Academics with a BSc had a better publication record over 10 years (median number of original publications 72) than the Oxford and Cambridge group (median 59) and a substantially better record than those from other schools without a BSc (median 46). Citation analysis was carried out on subsets of the above sample matched for date of graduation and frequency of publication. Those with an intercalated BSc were cited more often (8.04 citations/paper) than the Oxford and Cambridge graduates (7.63) and substantially more than their peers without a BSc (4.16). These data show very clearly that research training or experience, or both, as an undergraduate has a substantial influence on career development and correlates positively with subsequent research performance many years later.
