POSTERIORLY INSERTED VITREOUS BASE: Preoperative Characteristics, Intraoperative Findings, and Outcomes After Vitrectomy.
Observational study in Retina (Philadelphia, Pa.), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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 determine the preoperative characteristics, intraoperative and postoperative complications, and outcomes of eyes with posteriorly inserted vitreous base.
methodsIn this retrospective, observational, consecutive case series at 2 academic centers, 37 patients were studied who had posteriorly inserted vitreous base noted during vitrectomy. Posteriorly inserted vitreous base was defined as the insertion of the posterior hyaloid membrane being located posterior to the vortex veins. Fifteen eyes were analyzed in a histopathologic study of donor eyes to determine the average distance of the ora serrata from the vortex veins as this distance is uncertain.
resultsPosteriorly inserted vitreous base was identified during vitrectomy in 31 eyes with rhegmatogenous retinal detachment (84%), 4 with macular hole (11%), 1 with vitreous hemorrhage, and 1 with epiretinal membrane. Adjunctive buckle was used in 24%; 54% had 360° laser. Average number of tears seen preoperatively in those with rhegmatogenous retinal detachment was 3.1. Thirty percent had new breaks identified intraoperatively. Forty-one percent had lattice degeneration; new breaks were found in 40% of eyes with lattice. Thirteen percent of rhegmatogenous retinal detachments developed proliferative vitreoretinopathy. Average distance from the ora serrata to the vortex veins was 7.6 mm.
conclusionAny eye undergoing vitrectomy may have posteriorly inserted vitreous base, but those with a high number of retinal breaks and lattice near the equator may be at highest risk. Redetachment and proliferative vitreoretinopathy still occur despite knowledge of the disorder and adjuvant treatments.
