Data were extracted including the study population, study size, study design, propensity for bias, procedures employed to minimise bias, a rating of study quality, duration of follow-up, outcome rate in the reference group, effect estimate (either rate ratio, odds ratio, hazard ratio or risk difference depending on the study design utilised) and appropriate 95% confidence intervals.
There is a propensity for small negative studies not to reach full publication, and this might lead to an exaggerated estimate of effect [19].
In this study, the propensity for membrane fouling by EfOM was investigated using a flow field-flow fractionation (FlFFF) technique by comparing two different nanofiltration (NF) membranes: meta-phenylene diamine (MPD) versus piperazine based polyamides.
For example, Kidd ([1993]) used age as a proxy for financial capital and adopted a binary variable, "rent", to study immigrants' propensity for self-employment.
Their behavioral history might suggest a propensity for violence, according to the study.
To study the propensity for cannibalism, the number of eggs eaten by individuals for each of the different treatments was compared using ANOVA, as follows.
Table 4 summarises the longitudinal analysis of the effect of social networks on place of residence, adjusted for propensity score strata, study wave, and residence at previous wave.
A separate multinomial logistic regression model of place of residence at waves 2 6 on each social network was fit, adjusting for propensity score strata, study wave, and place of residence at the previous wave.
Hospital level clustering and the propensity matched study design were accounted for with marginal model analysis using the id statement of the SAS PHREG procedure and sandwich covariance matrix estimation.
Although local sidechain-to-mainchain interactions have been the focus of most previous studies, the propensity for sidechain-to-mainchain hydrogen bond formation is often met by distant interaction.
However, despite the increased use of colorectal cell lines for epigenetic studies, there have been no comprehensive studies of the propensity for methylation in these cell lines.
