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
Purpose: Intraocular lens (IOL) implantation in cases of insufficient capsular support remains challenging. This study introduces a modified belt loop technique (BLT) for scleral fixation of IOLs in eyes with insufficient capsular support, utilizing long, limbus-parallel scleral tunnels to improve stability and safety. Methods: This case series included patients who underwent IOL scleral fixation with the modified BLT at a single center. The technique employed a 7-0 polypropylene suture passed through eyeleted or fenestrated haptics, with flanges created by thermocautery and secured within scleral tunnels oriented parallel to the limbus. Outcome measures included visual acuity, spherical equivalent, intraocular pressure, endothelial cell density, IOL tilt and decentration, and complications. Minimum follow-up was 3 months. Results: This technique was successfully applied in 32 eyes of 32 patients (mean age 55.03 ± 12.83 years; 24 males). Mean follow-up was 6.35 ± 1.96 months (range 3-10 months). Best-corrected visual acuity improved from 0.51 ± 0.63 logMAR preoperatively to 0.31 ± 0.39 logMAR at final follow-up (P < 0.05). No significant change in intraocular pressure (IOP) was observed throughout follow-up (preoperative 16.06 ± 2.16 mmHg vs. final 15.37 ± 3.34 mmHg; P > 0.05). Endothelial cell loss was 8.83% ± 10.03% at final follow-up. Regarding IOL position, mean vertical and horizontal tilt angles were 2.23 ± 1.09° and 2.11 ± 1.02°, respectively; mean decentration values were 0.29 ± 0.18 mm vertically and 0.21 ± 0.09 mm horizontally. Except for transient mild intraoperative bleeding (n = 2, 6.25%) and transient postoperative intraocular pressure elevation (n = 3, 9.38%), no other complications or clinically significant IOL tilt or decentration were observed during follow-up. Conclusions: The modified belt loop technique is a safe and effective method for IOL fixation. It provides stable four-point fixation, minimizes risks of flange extrusion and disinsertion, and is applicable to various IOL designs with eyeleted or fenestrated haptics.
