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

Phenolphthalein poly (aryl ether ketone) (PEK-C) is highly compatible with epoxy resin, which is applied in epoxy resin-based composites to improve their strength. Solution spinning and electrospinning techniques are often used to produce PEK-C fibers, but these techniques pollute the environment and are not productive. To address the above challenges, melt spinning may be employed, but due to the high degree of molecular chain entanglement and poor melt fluidity of PEK-C, melt spinning remains difficult. Herein, this study presents the continuous melt spinning of PEK-C fibers through rheology modulation and melt strength enhancement. A series of PEK-C samples with different molecular weights were prepared by adjusting the molar ratio of monomers. The influence of molecular weights on rheological properties was investigated via capillary rheology tests. PEK-C with molecular weight (2.01 × 10
