Figure Lengend Snippet: Overview of methods to assess bone properties of cadaveric femurs at different length scales. The midpoint of fresh-frozen, cadaveric femurs was measured and used to identify a 70 mm section of the proximal mid-diaphysis (A). The proximal femur was then separated from the distal portion at the midpoint using a low-speed diamond tipped wafer saw (B) and subjected to DXA scans (C). A cross-section with a length ( L ) of ~70 mm was isolated from the proximal femur (D) and scanned using micro-computed tomography (μCT) (E). Cyclic reference point indentation (cRPI) and impact micro-indentation (IMI) were done along parallel tracks on the medial surface of the mid-diaphysis using a BioDent and an OsteoProbe instrument, respectively (F). Following these indentation procedures, testing coupons were machined out of the medial quadrant (G) for tensile and fracture toughness testing (H). Specimens underwent high-resolution μCT to identify any sample variation prior to mechanical testing (I). Following tensile and fracture toughness testing ( J ), specimens were cut from SENB for hydrothermal isometric tension (HIT) testing, differential scanning calorimetry (DSC), high-performance liquid chromatography (HPLC) plus fluorescent AGEs, and proton NMR ( 1 H NMR) relaxometry (K).

Figure Lengend Snippet: (A–F) Bland –Altman plots showing the mean ratio between 2 methods for estimating REE against the criterion (measured REE). The REE was estimated in CRC survivors ( n = 31; FAO/WHO/UNU BIA , n = 29). (A) Harris–Benedict vs. WRIC. (B) Mifflin–St. Jeor vs. WRIC. (C) FAO/WHO/UNU vs. WRIC. (D) Henry vs. WRIC. (E) Mifflin–St. Jeor DXA vs. WRIC. (F) FAO/WHO/UNU BIA vs. WRIC. BIA, bioelectrical impedance analysis; CRC, colorectal cancer; DXA, dual-energy X-ray absorptiometry; LoA, limits of agreement; MAPE, mean absolute percentage error; p , P value from correlation analysis presenting the significance of correlation; r , correlation coefficient form Spearman correlation analysis showing relation between WRIC and the other methods; REE, resting energy expenditure; UNU, United Nations University; WRIC, whole-room indirect calorimetry.

Figure Lengend Snippet: The accuracy of the predicted REE in CRC survivors ( n = 31; FAO/WHO/UNU BIA , n = 29) is illustrated as the percentage of REE values that fell within and outside ± 10% of REE WRIC . Predicted values within these accuracy limits were considered accurate, and values above and below these accuracy limits were considered overestimation and underestimations, respectively.
