Factors associated with visual field or structure progression occurring first in a prospective study on patients with untreated open-angle glaucoma with normal intraocular pressure.

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
BACKGROUND/
objectivesTo identify factors associated with disc/retina deterioration in stereo fundus photographs preceding that of the visual field (VF), as determined with a Humphrey Field Analyzer (HFA) (Structure First deterioration) and factors associated with the latter preceding the former (Field First deterioration) in open-angle glaucoma (OAG) with lower normal intraocular pressure (IOP). SUBJECTS/
methodsProspective cohort study. Ninety eyes of 90 patients with OAG and a baseline IOP < 15 mmHg participated in a 5-year prospective study without treatment. IOP measurements and HFA 24-2 Swedish Interactive Test Algorithm Standard tests were performed every 3 months, and fundus photographs were obtained every 6 months. VF deterioration was determined by Guided Progression Analysis and deterioration of disc/retina was determined on stereophotographs by an independent committee. A multivariable Cox proportional hazard model was used to identify factors associated with Structure First deterioration, and with Field First deterioration.
resultsThe average baseline age and mean deviation were 53.9 ± 9.8 years and -2.8 ± 2.8 dB, respectively. During the 5-year follow-up, the probability of Field First deterioration was 49% ± 6.6% (standard error) and that of Structure First deterioration was 33% ± 6.4% (P = 0.062, log-rank test). Disc hemorrhage (DH) prior to the event (P = 0.006) was associated with Structure First deterioration, and older age was associated with Field First deterioration (P = 0.040).
conclusionsIn OAG eyes with lower normal IOP, DH was significantly associated with Structure First deterioration, and age was significantly associated with Field First deterioration.
