Of the 433 eligible patients 278 (64%) were actually randomised, with large differences between the institutes, varying from 41 to 100%.
The height of water pouring did not affect significantly and/or appreciably the field saturated soil hydraulic conductivity, Kfs, measured with the SFH technique (differences between means varying with the site by a factor of 1.2 1.9) but it had an appreciable impact with BEST since low runs yielded higher means than the high ones by a factor of 11.5 35.2.
In a comparison study of five meters with sample testing by a medical technician, using 93 individuals, with 12 samples obtained per patient, 2 with each meter, the coefficient of variability (c.v., defined as the SD × 100/mean) ranged from 6.3 to 11.3%, with the differences between meters varying with glucose concentration and meter pairs, showing a 1 32% bias (37).
On the other hand, there are significant differences between regions; varying between almost 80 per cent in Mount Lebanon to only 57.5 per cent in the Districts of Akkar and Minieh - Dinnieh.
The study design offers the possibility of detecting subtle differences between the groups with varying pubertal timing.
Although trial participation was considered in almost all eligible patients, only two thirds were entered, with large differences between the centres and varying reasons for non-entry.
Differences between the microarray datasets, varying outcome information, and incomplete control of confounding by prognostic factors may limit interpretation of these findings; however, we attempted to control for patient and tumour heterogeneity between these studies by performing two analyses: a random-effects and a fixed-effects meta-analysis.
This was despite major differences between the studies, including varying response rates, sampling frames and modes of administration; the PHS had a smaller proportion of missing and invalid responses due to the nature of the computer assisted telephone interviewing system and it included respondents who completed the survey in languages other than English.
Malaria incidence showed a marked seasonal distribution, with an overall incidence rate estimated at 84/1,000 person-months and large differences between months, varying from 12 to 230 per 1,000 person-months (Table 2).
