Effect of the iris-ciliary angle on the prediction of the vault for phakic implantable collamer lens in the manufacturer's calculator.
Article in BMC ophthalmology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThis study aims to explore the effects of the iris-ciliary angle (ICA) on the accurate prediction of the vault after implantable collamer lens (ICL) using the manufacturer's online calculation and ordering system (OCOS).
methodsThe participants were categorized into three groups according to the size of ICA as follows: narrow ICA group (< 40°); normal ICA group (40°-60°); wide ICA group (> 60°). We compared the preoperative ocular characteristics and postoperative vault at 3 months among the three groups. Bivariate correlation was used to analyze the correlation between vault and ICA, and multiple linear regression was used to further analyze the correlation between vault and preoperative parameters. Ordered multicategorical logistic regression analyses were used to further illustrate the effect of different ICA groups on postoperative vault distribution.
resultsThis study included 278 eyes of 157 individuals. There were no statistically significant differences in preoperative ocular parameters among the three ICA groups, while the postoperative vault was minimal in the wide ICA group, followed by the normal and then the narrow ICA group (p < 0.001). The correlation between ICA and vault at 3 months postoperatively was significant in both bivariate correlation and multiple linear regression analysis (both P < 0.001). Ordered multicategorical logistic regression analyses showed that the odds of having a higher vault were 2.586 (P = 0.002) and 5.534 (P < 0.001) times in the normal and narrow ICA groups, respectively, compared to the wide ICA group.
conclusionsThe size of the ICA has a significant impact on vault created by the recommended ICL size for OCOS. Therefore, ICA should be considered when selecting ICL size using the OCOS recommended sizes preoperatively.
