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 investigate the predictive factors for intraocular pressure (IOP) after microhook ab interno trabeculotomy (TLO). Methods: We included 147 eyes of 97 glaucoma patients who underwent TLO. We recorded the following preoperative parameters: systemic parameters (age, height, body mass index, systolic blood pressure, diastolic blood pressure, and history of smoking), blood examination scores, ocular parameters (preoperative Goldmann applanation tonometry [GAT]-IOP, central corneal thickness, type of glaucoma, and preoperative use of anti-glaucoma eyedrops), and Ocular Response Analyzer (ORA) parameters (corneal resistance factor [CRF], corneal hysteresis, corneal-compensated intraocular pressure). We analyzed the preoperative parameters associated with postoperative GAT-IOP. Subsequently, similar analysis was performed using a corneal visualization Scheimpflug technology instrument (Corvis ST) parameters, instead of the ORA parameters. Postoperative GAT-IOP was measured after 12 months from TLO. Results: When ORA parameters were used, preoperative high hemoglobin (Hb), high C-reactive protein (CRP), use of brimonidine tartrate, and high CRF were significant risk factors for postoperative high GAT-IOP, in addition to type of glaucoma. When Corvis ST parameters were used, preoperative high serum Hb, high serum CRP, usage of brimonidine tartrate, high biomechanical intraocular pressure, high stress-strain index, and low time to maximal displacement of whole eye movement were significant risk factors for postoperative high GAT-IOP. Conclusions: ORA and Corvis ST measurements suggested that stiff cornea was a risk factor for high postoperative GAT-IOP after TLO, in addition to preoperative high Hb, high CRP, and the use of brimonidine tartrate. Translational Relevance: Stiff cornea is a risk factor for high postoperative intraocular pressure after trabeculotomy.
