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
Controversy persists regarding the ideal type of fixation for hernia mesh. Transfixing methods have been linked to tissue trauma and to the development of chronic pain. In ventral hernia repair (VHR), retrospective studies showed a potential for fixation with cyanoacrylate of being as effective as conventional suture or tacks methods but with less postoperative pain and complications. A pragmatic randomized trial was conducted on patients undergoing primary and incisional VHR, analyzing mesh fixation by cyanoacrylate (experimental group) versus sutures or reabsorbable tacks (control group), stratifying a priori by laparoscopic(LVHR) and open approach(OVHR) to account for distinct anatomical and biomechanical environments. Primary outcome was chronic postoperative pain. Secondary outcomes were postoperative complications, recurrence, operating time, intraoperative blood loss, pain during admission. Univariable and multivariable analysis were conducted. Two hundred fourteen patients were included, of which 109 treated laparoscopically. Overall chronic pain occurred exclusively within the open surgery cohort (12/105 cases, 11.4%), with no statistical difference between fixation arms. Cyanoacrylate for mesh fixation was independent factor for fewer perioperative complications (OR 0.457, 95% CI 0.244-0.855, p = 0.014), shorter operating time (- 7.172 min, 95%CI - 23.040/- 2.008, p = 0.02), reduced pain at hospital discharge (- 0.356 VAS point, 95%CI - 0.691/- 0.022, p = 0.037). In LVHR, non-transfixing mesh positioning was also a factor for less intraoperative blood loss. In OVHR there were no significant difference in outcomes between groups. In a pragmatic real-world setting, long-term chronic pain appears primarily driven by surgical access and wound-related factors rather than the independent effect of the mesh fixation method. Cyanoacrylate fixation provides significant perioperative advantages, particularly in LVHR.
