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

Fine micromachining of sapphire using ultrafast lasers via nonlinear absorptions has been extensively studied. However, severe damage, along with the low material removal rate, limits the precision and machining speed. Here we use transient and selective laser processing for sapphire by coaxially delivering a single femtosecond laser pulse and a single microsecond laser pulse that are temporally synchronized. It shows that the micromachining speed was improved 10
