Modified Scleral Needling Technique to Achieve Scleral Wound Closure in Microincision Vitrectomy Surgery.

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
purposeThe study aimed to evaluate the effectiveness of the modified scleral needling (SN) technique for unclosed scleral wounds in 25-gauge vitrectomy.
methodsThis retrospective study examined 50 scleral wounds that failed to self-close at the end of vitrectomy surgery performed by the same surgeon using a three-port 25-gauge vitrectomy system (Constellation® Vision System, Alcon Laboratories, Inc., Fort Worth, TX, USA) at Nihon University Hospital between February and August 2023. In all cases, scleral wounds were created by oblique puncture, and sufficient peripheral vitrectomy was performed. After the removal of the cannula, wound closure was assessed under air perfusion. The modified SN technique was implemented if the scleral wounds, excluding the infusion port, did not self-close. If self-closure was not achieved after three attempts of the modified SN technique, the scleral wound was sutured.
resultsThe modified SN technique closed 98% (49 of 50) of the leaking scleral wounds, and the average number of punctures was 1.36. Cochran's Q test revealed a statistically significant difference in the rate at which air leaks were sealed across the four stages (Q = 117.97; p = 2.11 × 10⁻²⁵). Subsequent pairwise comparisons using McNemar's test showed a significant improvement between the zero (no treatment) and first applications (p = 0.0005), as well as between the first and second applications (p = 0.0156). However, there was no statistically significant difference between the second and third applications (p = 0.125).
conclusionThe modified SN technique is safe and effective for promoting scleral wound closure in microincision vitrectomy surgery.
