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
purposeTo compare postoperative rotational stability of toric intraocular lenses (T-IOLs) following phacovitrectomy with and without gas tamponade.
methodsThis retrospective observational study evaluated postoperative T-IOL axis rotation at 3 months relative to intraoperative alignment using intraoperative and postoperative anterior segment photographs. Postoperative residual astigmatism, visual acuity, and refractive prediction error were compared between eyes with (gas [+]) and without (gas [-]) gas tamponade.
resultsA total of 143 eyes of 143 patients (mean age 69.0 ± 9.1 years) who underwent phacovitrectomy with Clareon T-IOL implantation were included. Gas (-) group comprised 90 eyes (mean age 71.3 ± 8.3 years), and gas (+) group comprised 53 eyes (mean age, 65.1 ± 9.3 years). The means for T-IOL axis rotation were 3.4 ± 2.5° and 4.3 ± 3.5° in the gas (-) and gas (+) groups, respectively, without significant difference (p = 0.115). Axis rotation ≥ 10° occurred in 2 eyes (2.2%) and 4 eyes (7.5%) in the gas (-) and gas (+) groups, respectively, (p = 0.194). The means for objective residual astigmatism were 0.74 ± 0.44 and 0.68 ± 0.42 diopters (D) in the gas (-) and gas (+) groups, respectively (p = 0.454). In eyes targeting emmetropia, postoperative uncorrected visual acuity was comparable between groups. Refractive prediction error also did not differ significantly.
conclusionPhacovitrectomy with T-IOL implantation demonstrated comparable rotational stability, residual astigmatism, refractive accuracy, and visual outcomes between eyes with and without gas tamponade use. T-IOL implantation may be a feasible option in selected eyes requiring gas tamponade.
