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 initial stage of planet formation is expected to take place in a nascent protoplanetary disk (PPD) accreting onto the protostar embedded in an infalling envelope. This stage is likely accompanied by the formation of high-condensation temperature solids resembling calcium-aluminum-rich inclusions (CAIs), the oldest known solar system solids. However, it is unknown whether magnetism and/or gravity dominantly drove accretion in the youngest evolutionary stages of PPDs and the solar nebula. Here we report paleomagnetic measurements of CAIs indicating that they record a nebular magnetic field of ∼150 to 600 μT. This intensity is consistent with magnetic fields playing a key role driving disk accretion while also heating the very inner disk to 10
