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
Objective: To evaluate the safety and efficacy of a modified anterior capsulorhexis technique using an 18-gauge needle puncture at the peripheral one-third of the anterior capsule to control intralenticular pressure and achieve single-stage continuous curvilinear capsulorhexis (CCC) in intumescent cataract surgery. Methods: This prospective, cross-sectional descriptive study included patients with intumescent cataracts indicated for surgery at Saigon Vinh Eye Hospital from August 2024 to March 2025. Before CCC, all patients underwent an 18-gauge needle puncture at the peripheral one-third of the anterior capsule near the main incision. Results: A total of 99 eyes from 99 patients were included in the study. The mean axial length was 23.12 ± 0.55 mm, anterior chamber depth 2.62 ± 0.43 mm, and lens thickness 4.91 ± 0.72 mm. In 65 patients (65.7%), the milky liquefied cortex escaped into the anterior chamber after the needle puncture. Single-stage CCC was successfully performed in 98 of 99 cases (98.9%) with a mean capsulorhexis diameter of 5.5 ± 0.3 mm. All surgeries were performed using standard phacoemulsification and in-the-bag IOL implantation (100%). Three months post-operatively, all patients had well-centered IOLs with a best-corrected visual acuity (BCVA) ≥ 4/10. Conclusion: An 18-gauge needle puncture at the peripheral one-third of the anterior capsule offers effective decompression, improves safety, and facilitates CCC in patients with intumescent cataracts. This technique is simple, feasible, and highly applicable in clinical practice.
