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
Purpose: This study aimed to compare the safety and efficacy of toric intra ocular lens (IOL) implantation vs. opposite clear corneal incision (OCCI) during cataract surgery to correct preexisting corneal astigmatism in patients with age related cataract by comparing the postoperative residual astigmatism, the uncorrected distance visual acuity and the adverse effects following both the procedures. Methods: A pilot prospective study was conducted at a tertiary hospital among patients undergoing cataract surgery over two years. A total of 150 eyes with pre-existing corneal astigmatism between 1 to 2.5 D were divided into two groups of 75 each by permuted block randomization. Group A underwent implantation of Results: In the OCCI Group, the difference between mean K1-K2 preoperative and 12 weeks postoperative (mean ± SD) of patients was 1.55 ± 0.17D. In the TORIC IOL Group, the difference between the mean K1-K2 preoperative and 12-week postoperative values (mean ± SD) for patients was 0.53 ± 0.11. The difference in mean K1-K2 pre-operatively and at 12 weeks was statistically significant for both groups (p < 0.0001). There was a significant reduction in corneal astigmatism in the OCCI group at 01 week. Discussion: In our study, the difference in mean K1-K2 at 1 week between the two Groups was statistically significant (p < 0.0001), as OCCI acts directly on the corneal plane, whereas Toric IOLs reduce astigmatism at the lens plane without affecting corneal curvature. There was a significant reduction in corneal astigmatism in the OCCI group at 1 week. This reduction continued to stabilize at 12 weeks. The corneal astigmatism remained stable in the post-operative period in the Toric IOL group. The decrease in astigmatism was more significant in the toric IOL group than in the OCCI group. Conclusions: These results demonstrate a similar efficacy of OCCI in reducing corneal astigmatism of up to 1.5 D compared to Toric IOLs. The uncorrected visual acuity was superior in the Toric IOL group. However, this difference was reduced significantly by 12 weeks.
