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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimTo assess whether the implantation of a posterior chamber phakic intraocular lens produces changes in optical coherence tomography (OCT) measurements of macular thickness (MT) and two parameters that define the structure of the optic nerve, the peripapillary nerve fiber layer (RNFL) and the Bruch's membrane opening-minimum rim width (BMO-MRW).
methodsThis nonrandomized prospective pre-post study included 86 eyes of 48 patients (age, 20-47y; axial length: 23.10-28.95 mm) scheduled for myopia or myopic astigmatism correction with implantation of the implantable collamer lens (ICL). Eyes with glaucoma or any other ocular disease that could alter OCT results were excluded. RNFL, BMO-MRW and MT were measured preoperatively, and at 1 and 6mo after surgery using spectral-domain OCT. Changes between preoperative and postoperative values were evaluated.
resultsThere was a significant increase in BMO-MRW at 1mo (mean change: 3.48±15.07 µm,
conclusionMinimal changes are induced in BMO-MRW, RNFL and MT after ICL implantation in healthy eyes, confirming the safety of the surgical procedure regarding the structure of the optic nerve head and the macula, and indicating that this phakic intraocular lens seems to have a slight impact on OCT measurements.
