Capture-recapture is a potentially useful method for assessing publication bias

Are CVD Patients Under Oxidative Stress?

“…Our study required the use of SMD for two reasons: (i) it allows pooling of results obtained from different studies and (ii) its use compensates, at least partially, for the use of different methods, different units of measurement and inter-lab differences ). We implemented SMD by using "Hedges' adjusted g" because it contains a correction for small sample bias (Bennett et al, 2004). Fig.…”

“…We used an adjustment of the "Egger's method" to detect publication bias and its direction. We defined the standard normal deviate (SND) as the mean difference, divided by its standard error regressed against the estimate's precision (Bennett et al, 2004). We defined the threshold pvalue for the intercept at a value of 0.1 to detect possible bias (Bennett et al, 2004).…”

“…This is of special importance in the present meta-analysis because the prevailing paradigm changed from viewing "oxidative stress" as a cause of atherosclerosis (Witztum, 1994) to viewing it as being merely a result of questionable significance (Witztum & Steinberg, 2001). In addition, we had to assess the completeness of the retrieved data and its validity with respect to the complete body of published data (Bennett et al, 2004). Towards this end, we have devised an algorithm similar to the "capture-recapture technique" proposed by Spoor et al (Spoor et al, 1996).…”

“…Subgroup analysis was performed by sample size. Asymmetry of the funnel plot was conducted to estimate the potential publication bias (Bannett et al, 2004). In order to complement the funnel plot, Begg's correlation and Egger's regression method were used (P<0.05 was considered to be statistically significant) (Begg et al, 1994;Egger et al, 1997).…”

Bibliographic search with Mark-and-Recapture

“…However the probability that a paper is found and referenced is not equal [10]. There are many factors that affects the visibility of a publication in a search engine (respectively literature review), e.g.…”
