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

We report the use of the Harms trabeculotome to facilitate 360° microcatheter advancement during illuminated microcatheter-assisted circumferential trabeculotomy (IMCT) ab externo in a 3-month-old infant with bilateral primary congenital glaucoma who required repeat surgery. The illuminated microcatheter was advanced 270°, from 9 to 6 o'clock; however, a focal blockage occurred, and, despite viscodilation, further advancement was not possible. The surgeon introduced a right Harms trabeculotome in the opposite direction, counterclockwise through the same scleral flap. The trabeculotome approximated and manipulated the illuminated microcatheter tip. The illuminated microcatheter was then able to advance beyond the focal obstruction, and the 360° circumferential trabeculotomy was completed.
