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

In this case report, we aim to describe the use of double-ring segments to treat a case of keratoconus in corneal allogenic intrastromal ring segments (CAIRS). A 23-year-old male with advanced keratoconus presented with decreased vision and agreed to be treated by CAIRS surgery. A modified CAIRS was performed with two ring segments inserted into the upper and inferior tunnels. A significant corneal flattening was observed during an early postoperative period, resulting in an improvement of visual acuity without any complications for more than six months following the procedure. In this case, CAIRS, with the use of double segments in the tunnel, was effective in terms of the ability to flatten the corneal curvature and result in a dramatic improvement in visual acuity.
