Investigating the correlation between scleral spur angle and intraocular lens tilt.

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
purposeTo evaluate the correlation between the preoperative vertex-scleral spur angle (Vtx-SSA) and postoperative horizontal intraocular lens (IOL) tilt after routine cataract surgery.
settingCullen Eye Institute, Baylor College of Medicine, Houston, Texas.
designProspective case series.
methodsThis study enrolled patients who underwent uneventful phacoemulsification cataract extraction with IOL implantation. The Anterion and Eyestar 900 swept-source optical coherence tomographers (SS-OCTs) were used to determine Vtx-SSA and lens tilt (crystalline and IOL) measurements, respectively. Tilt vectors were decomposed into orthogonal, vertical, and horizontal components to explore preoperative correlations independently. The Pearson correlation coefficient and linear regression analysis were used to evaluate the relationships between select variables.
resultsIn a cohort of 72 eyes of 72 patients, the preoperative Vtx-SSA was highly correlated with horizontal IOL tilt ( r2 = 0.97, P < .01). On average, tilting of the IOL in the horizontal axis accounted for nearly 80% of the total tilt magnitude. Crystalline lens measurements revealed a similarly strong correlation between horizontal tilts of the crystalline lens and IOL ( r2 = 0.97, P < .01). However, IOL tilt along the vertical meridian may be more difficult to anticipate using crystalline lens measurements ( r2 = 0.78, P < .01) and showed no correlation with axial length ( r2 = 0.00, P = .92).
conclusionsThe Vtx-SSA may be used as an easy-to-interpret presurgical surrogate for estimating horizontal IOL tilt. Still, it does not account for more minor contributions of tilt in the vertical plane.
