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

Optical microcavities with strong light confinement are powerful tools for significantly enhancing light-matter interactions. Currently, the actual Q factor of a microcavity remains far below the theoretical limit, as specific factors affecting losses inside microcavities are not yet fully quantified. Here, using silica whispering-gallery-mode microrod cavities, we quantitatively identify how radiation loss, scattering loss, and contaminant loss contribute to the total loss, finding that after fine fabrication, contaminant loss is the major factor limiting the total cavity Q. By employing two-step laser polishing and heat treatment, we achieve a Q factor of up to 8.28 × 10
