Abstract

Aim: To validate the PAWPER tape and assess its inter-observer reliability in children accessing a Paediatric Emergency Department (PED). As secondary outcome we compared the accuracy of the PAWPER tape with that of parents' estimation, the Broselow tape and the European Paediatric Life Support (EPLS) formula.Methods: This was a cross-sectional study of children (0-12 years) enrolled in a tertiary Paediatric Emergency Department in Italy. Children's weight was estimated by parents and by trained healthcare providers using the PAWPER tape, the Broselow tape and the EPLS formula. The root mean squared percentage error (RMSPE) for the estimation of precision was calculated. Overall accuracy was evaluated using the percentage of weight estimation falling within 10% (PW10) and 20% (PW20) of real weight.Results: The study included 2060 children. Parental estimation was the most accurate and precise method. The PAWPER tape was accurate throughout all habitus sizes except for extreme underweight and overweight categories. Furthermore, it was more accurate and more precise than the Broselow tape and the EPLS formula (p adjusted <0.001).Conclusions: The PAWPER tape served as an accurate method for weight estimation in children accessing a Paediatric Emergency Department, with excellent inter-rater reliability. It performed significantly better than other length or age-based tools, showing good accuracy and precision except for very extreme weights. Whilst parents' estimation yielded to be the most accurate and precise method, the age-based EPLS formula was not reliable for estimating weight in all subcategories of habitus.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
