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

To evaluate endothelial cell density (ECD) and corneal biomechanical changes following implantation of Veriflex and Implantable Collamer Lens (ICL) phakic intraocular lenses (pIOLs) over a 12-month period. Sixty patients (117 eyes) were included in this prospective comparative study. 58 eyes underwent implantation with the Veriflex lens (Group I), while 59 eyes received the ICL (Group II). Preoperative and postoperative ECD and corneal biomechanical values were assessed using specular microscopy and Corvis St at baseline, 6 months, and 1 year. Endothelial cell loss percentages and corneal biomechanical changes were calculated and compared between the 2 groups. Preoperatively, the mean ECD was 2683.4 ± 340.6 cells/mm
