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
aimTo compare the visual outcomes between bilateral implantation of Tecnis ZXR00 extended depth-of-focus (EDOF) intraocular lenses (IOLs) and mixed implantation of Tecnis ZXR00 (EDOF) with Tecnis ZMB00 (bifocal) IOLs.
methodsThis postoperative cross-sectional study enrolled patients who underwent phacoemulsification combined with IOL implantation. Patients were divided into two groups: the bilateral ZXR00 group (ZXR00-only group) and the mixed IOL group (ZXR00+ZMB00 group). Primary outcome measures included uncorrected and corrected distance visual acuity (UDVA, CDVA), uncorrected and distance-corrected near visual acuity (UNVA, DCNVA), uncorrected and distance-corrected intermediate visual acuity (UIVA, DCIVA), and defocus curves. Secondary outcome measures were visual quality, spectacle independence, patient satisfaction, photic phenomena, and stereopsis.
resultsA total of 47 patients (94 eyes) were included, with 26 patients (11 males, 15 females) in the ZXR00-only group (mean age: 62.73±7.24y) and 21 patients (7 males, 14 females) in the mixed group (mean age: 65.71±9.16y). There was no statistically significant difference in age between the two groups (
conclusionMixed implantation of EDOF and bifocal IOLs improve near visual acuity but may compromise near stereopsis. This approach provides a viable option for patients prioritizing near vision; however, caution is recommended for individuals requiring fine stereoscopic vision for daily or professional tasks.
