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.

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.

Abstract

A modified Yamane technique with a 26-gauge needle for aphakia correction is described. Single corneal or corneoscleral incision is set at 12 o'clock. The 26-gauge needles are used to make 2 angled incisions parallel to the limbus to fix the haptics of a 3-piece intraocular lens. The modifications provide an easier and safer way of haptic insertion into the needle tip and decreases the possibility of bending or breaking the haptic.
