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: To evaluate the stability of different intraocular lenses (IOLs) after phacovitrectomy with air or gas tamponade. Patients and Methods: This retrospective cross-sectional study included 28 patients who underwent phacovitrectomy with air or sulfur hexafluoride gas tamponade and postoperative anterior segment optical coherence tomography assessments. Patients who received any DIB00V (Johnson & Johnson Surgical Vision, Inc. Irvine, CA, USA), XY-1 (HOYA Surgical Optics Co. Chromos, Singapore), or NX70s (Santen Pharmaceutical Co. LTD, Osaka, Japan) IOL implantation were analyzed. The anterior chamber depth (ACD) and IOL position values at each measurement (100%, 50%, 0%) and between IOLs were compared. The IOL displacement force (mN) was measured with a verification experiment and recorded at each 0.1 mm anterior movement until anterior displacement reached 0.5 mm. Results: The average patient age was 66 (59-73) years. ACD values increased progressively as the postoperative gas decreased for all IOLs. Compared to the preoperative ACD, postoperative ACD was significantly greater at 50% and 0% gas for all IOLs. The DIB00V had significantly larger ACD values than the XY-1 at 100% gas or air (P = 0.023) and the NX70s at 0% gas or air (P = 0.008). The IOL position gradually shifted significantly posteriorly for all IOLs as the gas or air disappeared. No significant change was observed in the DIB00V and NX70s between the gas 50% and gas 0% conditions (DIB00VP = 0.019 with Bonferroni correction, NX70s; P = 0.148 with Bonferroni correction). The DIB00V were significantly more posterior than the XY-1at 100% (P = 0.046). Conclusion: The DIB00V had greater IOL displacement force against push from the retinal surface compared to the XY-1 and NX70s and exhibited excellent z-axis stability in phacovitrectomy with air or gas tamponade.
