Refractive Outcomes Following Combined Cataract and Microinvasive Glaucoma Surgery.
Article in Ophthalmology. Glaucoma. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 compare refractive outcomes in eyes undergoing cataract extraction (CE) alone, CE with goniotomy (CE/goniotomy), and CE with Schlemm's canal stent (CE/SCS) insertion.
designRetrospective cohort study.
participantsEyes from the Bascom Palmer Glaucoma Repository undergoing CE/goniotomy, CE/SCS insertion, or uncomplicated CE alone between July 2014 and February 2022 were identified.
methodsRefraction data were analyzed at postoperative month (POM) 1 and 6 with Kruskal-Wallis and Dunn's tests. Anisometropia was defined as a spherical equivalent (SE) difference of ≥2D.
main outcome measuresThe primary outcome was mean refraction at POM1 and POM6 across the 3 surgical groups. Secondary outcomes were comparisons of refraction and visual acuity (VA) among different goniotomy and Schlemm's canal stent (SCS) devices, as well as incidence of anisometropia.
resultsA total of 8360 eyes (150 CE/goniotomy, 395 CE/SCS, and 7815 CE alone) from 6059 patients were analyzed. At POM1, mean SE in the CE/goniotomy, CE/SCS, and CE alone groups was -0.36 ± 0.91D, -0.31 ± 0.85D, and -0.39 ± 0.88D respectively (P = 0.019). Mean logarithm of the minimum angle of resolution VA was 0.10 ± 0.20, 0.08 ± 0.19, and 0.14 ± 0.26 respectively (P = 0.002, CE/SCS vs. CE alone). No statistically significant differences were noted at POM6. Anisometropia occurred at POM1 in 2 patients (13.3%) in the CE/goniotomy-CE group, 1 patient (3.2%) in the CE/SCS-CE group, and 184 patients (4.9%) in the CE-CE group (P = 0.217). At POM6, mean SEs were -0.38 ± 0.97D (CE/goniotomy), -0.35 ± 0.81D (CE/SCS), and -0.40 ± 0.91D (CE alone; P = 0.473). No significant differences in overall refractive outcomes were observed with different SCS or goniotomy devices. Among primary open-angle glaucoma/normal-tension glaucoma eyes, mean SE at POM1 was -0.36 ± 0.73D (CE/goniotomy), -0.24 ± 0.84D (CE/SCS), and -0.45 ± 0.81D (CE alone; P < 0.001).
conclusionsConcurrent SCS insertion or goniotomy with CE was associated with some statistically significant differences in postoperative refraction and VA, although these small magnitude differences were unlikely to be clinically meaningful.
