We understand the chance to review issues related to the fit use of statistical analysis to decide supine of ahead agent measuring methods. Our correspondent feels we misrepresented the findings by Rhodes et al by stating there was “poor pact base … liaison visual methods of leg checking and standing up radiographs.” The authors create that the correlation coefficient (r) was 0.719 and conclude, “most statisticians brand this as a ‘moderate positive’ correlation.” We did not under consideration this conclusion as suited as the investigators' own qualitative interpretation: “Results indicated … the relationship was not as strong as anticipated. Mileage differences intermediary methods in this investigation, which were greater than 3 mm 48% of the time, indicated that inclined breadth by itself is not accurate as a predictor of X-ray leg greatest extent differences.” The results branch of the Rhodes et al article documents largish divergence of the prone leg check and radiographic findings. The very dispersed disband arrange in their Fig 2 speaks for itself; the decoding of the slope of the regression song is mathematically erroneous and thus misleading <<>>
