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

Understanding the curing and molding process of HTPB two-stage solid propellants and their stress and strain distributions is essential for the efficient manufacturing, long-term storage, safe transportation, and reliable operation of solid rocket motors. In this study, the residual stress and strain generated during the curing and molding of HTPB two-stage solid propellants were numerically investigated. The mechanisms responsible for residual stress and strain were analyzed, the relaxation modulus was characterized using a Prony series and the WLF time-temperature superposition equation, and the curing and cooling processes of a two-stage solid propellant grain were simulated. Furthermore, the effects of the modulus
