Correlation of central field index (10-2 visual field analysis) and activity limitation with increasing severity of glaucoma using glaucoma activity limitation-9 questionnaire.

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: The purpose of the study was to analyze the correlation between central field index (CFI) and activity limitation in glaucoma using glaucoma activity limitation-9 (GAL-9) questionnaire. Methods: This hospital-based, cross-sectional, noninterventional study, included 50 patients diagnosed with glaucoma, with field defect encroaching onto central 10° in Humphrey field analysis 30-2 program, in at least one eye. These patients underwent central 10-2 field analysis and CFI was calculated with the help of a calculator created by us. Patients with severe cognitive impairment were excluded and the rest completed the GAL-9 questionnaire. The data was analyzed to determine the correlation between the CFI and the GAL-9 scores. Results: There was a moderate correlation between CFI of better eye (r = -0.431, confidence interval "CI" -0.619 to -0.173, P < 0.002) and worse eye (r = -0.342, CI: -0.575 to - 0.058, P < 0.015) with GAL-9, the better eye showing a stronger correlation. Mean deviations (MD) of both better (r = -0.345, CI: -0.556 to -0.069, P < 0.014) and worse eye (r = -0.346, CI: -0.578 to -0.063 P < 0.014) showed similar moderate correlation. Vision of better eye (r = -0.398, CI: -0.577 to -0.210, P < 0.004) showed a stronger correlation with GAL-9 score than worse eye (r = -0.188, CI: -0.475 to 0.100, P < 0.192). Subscales of GAL-9 questionnaire also correlated with better eye status. "Finding dropped objects" had the strongest correlation to CFI of better eye (r = -0.676) and "adjusting to dim lights" had the weakest correlation (r = -0.052). Conclusion: The better eye status in glaucoma patients correlated better than worse eye with regard to activity limitation, signifying that the better eye has a greater influence on the quality of life and how patients perceive their disability. Furthermore, CFI showed a better correlation with GAL-9 score than MD.
