1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

A series of polyurethanes (PU-GT) were prepared using polyglycolide-block-polytetrahydrofuran-block-polyglycolide (PGA-PTHF-PGA), polytetrahydrofuran homopolymer (PTHF), glycerol, and hexamethylene diisocyanate (HDI) by a one-pot synthesis method. The non-isothermal crystallization and subsequent heating curves showed that the PTHF component in these polyurethanes could crystallize in a temperature range of -11.5~2.6 °C during the cooling process, and the melting temperatures of PTHF crystallites were in the range of 24.0~26.9 °C. The WAXD results implied that a small content of PGA could crystallize in the membranes of PU-GT polyurethanes. And compared with PU-GT-100, which did not contain the PGA-PTHF-PGA block polymer, other PU-GT polyurethanes showed excellent mechanical properties because of the existence of the PGA component. Moreover, these polyurethanes had temperature-responsive shape memory properties due to the PTHF crystallites. The temporary shape could be fixed at -20 °C and recovered to the permanent shape at 37 °C. We conducted two kinds of conceptual experiments using PU-GT-50 polyurethane, which showed its great potential for medical applications in vascular and wound repair.
