Mean rate of progression of visual fields in patients with primary open-angle glaucoma and ocular hypertension attending a tertiary care center in South India - A prospective cohort study using FORUM

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: To find out the mean rate of progression (MROP) of visual fields (VF) in patients with primary open-angle glaucoma (POAG) and ocular hypertension (OHT) using FORUM Methods: Two hundred and one eyes of 105 patients were included in this prospective cohort study. Patients with POAG and OHT were recruited, and VF analysis with 24-2 and or 10-2 was done using SITA standard strategy in Zeiss Humphrey Visual Field Analyzer (HFA). All the previous VFs were identified from FORUM software, and the baseline indices were recorded from the first reliable VF analysis. The present VF analysis was compared to the previous one using FORUM software, and the rate of progression (ROP) in VF was obtained by Guided Progression Analysis. Results: MROP of VF in the POAG group was - 0.085 dB/year, ranging from -2.8 to 2.8 dB/year with a standard deviation (SD) of 0.69. In the OHT group, the MROP of VF was -0.003 dB/year, ranging from - 0.8 to 0.5 dB/year with an SD of 0.27. The MROP of VF in medically treated eyes with POAG was -0.14 dB/year with an SD of 0.61 and in surgically treated eyes was -0.02 dB/year with an SD of 0.78. The overall baseline mean VF index (VFI) was 83.19% and the final mean VFI was 79.80%. There was a statistically significant decrease in the mean VFI value from baseline to the final visit (P-value 0.0005). Conclusion: The mean ROP of VF in the POAG group was -0.085 dB/year and in the OHT group was - 0.003 dB/year.
