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
purposeTo compare the prevalence and characteristics of persistent postoperative discomfort 1 year after keratorefractive lenticule extraction (KLEX) and implantable collamer lens (ICL) implantation.
methodsThis retrospective comparative study included 324 eyes from 324 patients with myopia or myopic astigmatism who underwent bilateral KLEX (n = 227) or ICL implantation (n = 97) at a single center. One year postoperatively, visual outcomes, patient satisfaction, and persistent discomfort symptoms were evaluated using a standardized questionnaire, including symptom frequency, severity, and resolution time.
resultsVisual outcomes and overall satisfaction were high and comparable between the two groups (97.3% for KLEX vs. 99.0% for ICL; p = 0.157). Persistent glare and halos were significantly less frequent in the KLEX group than in the ICL group (glare: 50.2% vs. 64.9%, p = 0.045; halos: 48.9% vs. 63.9%, p = 0.034). The time to resolution for these symptoms was significantly shorter in the KLEX group (p = 0.031 and p = 0.024, respectively). In contrast, dryness was more frequent, severe, and bothersome in the KLEX group than in the ICL group (all p < 0.001), and its resolution time was longer (p = 0.008).
conclusionsKLEX and ICL implantation showed distinct profiles of persistent postoperative discomfort at 1 year. ICL implantation was associated with higher rates and longer duration of glare and halos, while KLEX was associated with more severe and persistent dryness. These findings underscore the importance of individualized preoperative counseling and patient selection.
