Preliminary parameter estimates are provided below, based on your selection of studies and weighted by the scores.
You may want to exclude or give less weight to studies that are far from the regression line in the graph.
Selected studies = 12, geometric mean a = 0.0182, mean b = 2.99, SD log10(W) = 1.1452, SD log10(a) = 0.4385 SD b = 0.2076
Estimate weight for given length: (cm) = (g) 95% range - (g)
