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 determine the visual performance and patient reported outcomes after bilateral implantation of an enhanced monofocal intraocular lens (IOL) (RayOne EMV RAO200E) targeted for emmetropia or modest monovision. Patients and Methods: This was a prospective, single-centre, comparative, interventional study. Patients were divided into two groups and targeted for bilateral emmetropia or modest monovision (-1.50 D in the near eye). Manifest refraction, monocular uncorrected and corrected distance visual acuity (UDVA and CDVA), uncorrected and distance-corrected intermediate visual acuity (UIVA and DCIVA), uncorrected and distance-corrected near visual acuity (UNVA and DCNVA), and monocular and binocular defocus curves under photopic and mesopic conditions were measured at 1-month post-surgery. The Catquest 9-SF questionnaire was administered to assess patient reported visual outcomes and quality of life. Results: 60 patients were enrolled. For the emmetropia group (n = 30), the mean logMAR UDVA, UIVA and UNVA were 0.16±0.13, 0.35±0.12 and 0.50±0.15. In the monovision group (n = 30), the values for the distance eyes were 0.13±0.11, 0.40±0.11 and 0.56±0.13; and for the near eyes 0.41±0.21, 0.27±0.16 and 0.34±0.13. Binocular defocus curves showed similar distance visual acuity but better visual acuity in the monovision group from -1.00 D to -4.00 D and -1.00 D to -3.50 D defocus under photopic and mesopic conditions respectively (p < 0.05). The defocus range (logMAR 0.2 or better) was 1.3 D for the bilateral emmetropia group and 2.5 D for the monovision group. 90% (emmetropia group) and 96% (monovision group) of patients were very or fairly satisfied with their vision, with the monovision group reporting better performance for intermediate and near tasks. Conclusion: Patients targeted for bilateral emmetropia achieved good functional intermediate vision, while those with modest monovision experienced enhanced intermediate and near vision. Overall, patients reported high satisfaction and good visual performance when implanted with the enhanced monofocal IOL.
