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
purposeRefractive errors are common in Saudi Arabia and keratorefractive surgeries are usually done to correct them. However, not all patients are fit and complications postoperatively are a concern. Implantable collamer lens (ICL) implantation can be used for patients who are not fit for keratorefractive surgeries. ICL can also be used for keratoconus. We elected to evaluate the outcomes of patients who had ICL implantation for refractive errors or keratoconus.
methodsWe retrospectively reviewed patients aged between 21 and 45 years old, who attended the anterior segment clinic at King Khaled Eye Specialist Hospital and who had spherical equivalent (SE) ranging between (+16 to -23 diopters), and had ICL implantation between February 2015 and September 2017. The SE was documented before and after the surgery. Depending on the SE, patients were divided into two groups (myopia and hyperopia). Statistical analysis was done to evaluate the change in mean SE before and after surgery for patients.
resultsWe identified 169 eyes and 155 (92%) were myopic before the surgery. Before surgery, the mean SE was -8.6 and the standard deviation (SD) was 4.4. Only 14 eyes (8%) were hyperopic before the surgery with a mean SE of +5.5 and SD of 4.8. The difference in the mean of SE between after and before the surgery for myopic eyes was statistically significant (mean difference: 7.8, SD: 5,
conclusionThe effect of ICL implantation was significant in improving the SE for myopic, hyperopic, and keratoconus eyes.
