We also conducted effect modification by population size by choosing the median (4,628) of the ZIP code level total population as the cutoff between urban and rural areas.
In this sandwich structure, the electrochemical properties of Mn3O4 and MnO can be obviously improved because of the buffering, confining and conducting effects of the graphite nanosheet.
Finally, we had limited statistical power for individual cancer subtypes and for conducting effect modification analyses.
Oleic acid consumption is considered cardio-protective according to studies conducted examining effects of the Mediterranean diet.
A gene array analysis was conducted for effects of TFIIS siRNA on MCF7 and MCF10A cell lines.
Not study was conducted on effect of simulated Mars analog environment on stress and salivary amylase.
For these three studies we conducted an effects-size meta-analysis.
We conducted random-effects meta-analyses to pool the RRs reported in the included publications.
We conducted random-effects meta-analyses to pool the relative risks (RRs) reported in the included publications (Table 2).
Since no similar studies have been conducted, the effect size was set small-to-moderate (f = 0.15).
We used Comprehensive Meta-Analysis version 2.2 (Biostat, Englewood, NJ) for conducting fixed effects meta-analysis.
