This could be explained mainly by management practices (biased distribution of seeds and fertilisers by broadcast spreaders), whereas light reduction probably played a minimal role (explained only 2% of the crop yield variability).

But in practice, bias correction is often desired, which equals to estimating the population eigenvalues corresponding to a set of sample eigenvalues.
Competitors like local restaurant review site Yelp voiced concerns that Google first usurped their content "without permission" in order "to prop up its own, less effective product" and then later practiced bias when interlacing its own services within standard results pages.
Our study has important strengths including its multicenter design that contributes to reduce practice bias.
Reasons for variance may include residual practice bias and clinical factors which could introduce a treatment bias where anesthetic technique could be altered to account for specific patient risk factors.
Both studies showed reduction in pain but both were subject to limitations - Arai et al [ 39] only included 22 subjects although it was powered and randomised, with a sham treatment; Alavi et al's [ 38] trial was larger and randomised, but used a within-subjects crossover design which can create practice bias.
Limitations: The meta-analytic technique employed in this analysis is limited by the possible inclusion of studies with unreliable study designs or biased treatment practices, publication bias in which some studies may not have been reported, and possible lack of identification of all relevant studies.
