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: To evaluate clinical outcomes in eyes with pre-existing astigmatism undergoing cataract surgery or refractive lens exchange with the implantation of an isofocal optic-design toric intraocular lens (IOL) with double C-loop haptics. Method: This multicenter retrospective study comprised 100 eyes (65 patients) implanted with the Isopure Serenity toric IOL (BVI, Inc.) conducted across four sites. Postoperative evaluation at between 2 and 3 months included manifest refraction, monocular uncorrected and distance corrected visual acuity (UDVA and CDVA), monocular uncorrected and distance corrected intermediate visual acuity (UIVA and DCIVA, at 80 and 66 cm), monocular uncorrected and distance corrected near visual acuity (UNVA and DCNVA, at 40 cm), binocular defocus curve and rotational stability. Results: Manifest refraction spherical equivalent and refractive astigmatism were -0.24±0.41D and -0.36±0.36D, respectively. About 79% and 97% of eyes were within ±0.50D and ±1.00D, respectively, and 80% and 96% of eyes were ≤0.50D and ≤1.00D of refractive cylinder, respectively. At distance vision, the mean monocular CDVA was -0.02±0.06 logMAR and 92.93% of eyes showed a CDVA of ≥20/20. At intermediate vision, the mean monocular DCIVA values were 0.10±0.07 and 0.17±0.10 logMAR at 80 cm and 66 cm, respectively; and 96.92% and 88.33% of eyes showed a DCIVA of ≥20/32 at 80 cm and 66 cm, respectively. At near vision, the mean monocular DCNVA was 0.31±0.08 logMAR and 75.44% of eyes showed a DCNVA of ≥20/40. The binocular depth of focus range was approximately 1.50D. The mean absolute IOL rotation was 2.73±2.58 degrees with all eyes having a rotation of <10 degrees. Conclusions: Eyes with pre-existing astigmatism implanted with the Isopure Serenity toric IOL showed good distance visual acuity and functional intermediate vision, with high refractive accuracy and good rotational stability following cataract and refractive lens exchange surgery.
