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

China's ongoing Tianwen-2 mission will return samples from a small, rapidly spinning Earth quasi-satellite (469219) Kamo'oalewa. Previous studies linked Kamo'oalewa to lunar composition and origin. Here, we propose another scenario. We reanalyze the reflectance spectrum of Kamo'oalewa and obtain an absorption band center at 1.001 ± 0.028 μm (error is 1σ), consistent with LL chondrites. We then conduct space weathering experiments on meteorites and find that highly space-weathered LL chondrite powder (but not slab) successfully reproduces the reflectance spectrum of Kamo'oalewa. We further trace the dynamical origin of Kamo'oalewa and find that it probably originated from the ν
