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

The present study systematically investigates the crystallization kinetics and crystal morphology of polylactic acid (PLA) stereocomplex (SC) crystallization from the cold state in 1/1 poly l-lactic acid (PLLA) and poly d-lactic acid (PDLA) mixtures, i.e., via homorecrystallization and mesophase growth mechanisms at two different temperatures (190 and 215 °C). Thereto, homocrystals and mesophase precursors are generated at temperatures of 80, 100, and 120 °C. For the characterization of the crystalline structures, a combination of wide-angle X-ray diffraction (WAXD), small-angle X-ray scattering (SAXS), differential scanning calorimetry (DSC), and microscopy techniques is employed. The study reveals that homorecrystallization is much faster than crystallization via mesophase growth and can lead to the formation of either nodular-shaped stereocomplex crystals or coarser lamellar structures, depending on the crystallization temperature. The isothermal crystallization kinetics in a temperature jump stage is characterized via in situ WAXD and modeled with a modified Hillier-type model. The combination of thermal and structural characterization techniques allows to shed light on the factors that influence the crystalline structure of SC crystals, as well as the kinetics of their formation, which can be used for the development of high-performance PLA-based materials.
