Efficacy Comparison Between Steep-Meridian Incision and Non-Steep-Meridian Incision in Implantable Collamer Lens Surgery with Low-to-Moderate Astigmatism.
Article in Ophthalmology and therapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introductionTo compare the visual outcomes of astigmatism correction with implantable collamer lens (ICL) surgery with low-to-moderate astigmatism through a steep-meridian corneal relaxing incision (SM-CRI) and non-steep-meridian corneal relaxing incision (NSM-CRI).
methodsSeventy eyes of 70 patients with myopia and myopic astigmatism who underwent ICL V4c implantation were classified into two groups: SM-CRI and NSM-CRI. Refractive outcomes and vector analysis were evaluated preoperatively and 6 months postoperatively.
resultsAt the postoperative 6 month visit, all participants in both groups achieved an uncorrected distance visual acuity (UDVA) of 20/20 or better. The difference vector (DV) showed that the residual astigmatism in the SM-CRI group was much smaller than that in the NSM-CRI group (P = 0.021), and the correction index (CI) was 0.84 ± 0.30 and 0.67 ± 0.35 for the SM-CRI and NSM-CRI groups, respectively, with a significant statistical difference (P = 0.013). Approximately 71% of eyes in the SM-CRI group had an angle of error (AE) within ± 15°, whereas 55% of eyes in the NSM-CRI group were within that range. The absolute mean AE was 10.13 ± 14.57° in the SM-CRI group, compared with 23.88 ± 28.22° in the NSM-CRI group (P = 0.038).
conclusionSM-CRI can alleviate corneal astigmatism and decrease the cylindrical diopter of the ICL, thus improving postoperative visual quality compared with NSM-CRI.
