Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A type of four-arm star-shaped copolymer (star-PAA(PEA)-PNIPAM), consisting of the thermoresponsive block (poly(N-isopropylacrylamide), PNIPAM) and the phosphorylated functional block O-phosphoethanolamine (PEA) grafted poly(acrylic acid) (PAA(PEA)), is synthesized by atom transfer radical polymerization (ATRP) and subsequent modification. Owing to the unique superiority of the star-shaped structure, star-PAA(PEA)-PNIPAM can transform from the sol to gel state in response to the physiological temperature (37 °C) at a relatively low polymer concentration (>0.5 wt%). In addition, because of the enriched phosphorylated functional groups, the hydrogel formed by star-PAA(PEA)-PNIPAM can mimic the acidic extracellular matrix protein to adsorb calcium ions and mineralize in situ, both in in vitro and in in vivo experiments. Meanwhile, it is favorable for cell adhesion and proliferation due to its appropriate three-dimensional interspace. Thus, the biocompatible star-PAA(PEA)-PNIPAM hydrogel has great potential for bone repair applications.
