WebIn the IRT scaling stage, all available items and data from prior PISA cycles (2006, 2009, 2012) were scaled together with the 2015 data via a concurrent calibration using country-by-language-by-cycle groups. However, only results based on the item parameters for the 2015 items are presented here.WebApr 14, 2024 · After obtaining the IRT image, a region of interest (ROI) will be drawn to extract the skin temperature of the acupoint. The IRT image contains both lower limbs. For the KOA group, the side with more severe symptoms will be used as the evaluation side. For the healthy control group, one side will be randomly selected for evaluation.
