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
purposeThe study aimed to investigate the correlation between arterial hemodynamics measured by color Doppler ultrasonography and retinal microarchitecture parameters determined by spectral-domain optical coherence tomography (SD-OCT) in pseudoexfoliation glaucoma.
methodsThis prospective study included 82 participants. Peripapillary retinal nerve fiber layer, ganglion cell inner plexiform layer, and ganglion cell complex values were measured. Ophthalmic artery and central retinal artery flows were evaluated with color Doppler ultrasonography, and resistivity index values were calculated.
resultsThe study included 47 controls and 35 pseudoexfoliation glaucoma cases. In pseudoexfoliation glaucoma group, mean peripapillary retinal nerve fiber layer and ganglion cell complex thickness were statistically significantly lower in all quadrants compared to controls (p<0.001). Resistivity index values of the ophthalmic and central retinal arteries were significantly higher in pseudoexfoliation glaucoma group than in the controls (p<0.001 and r=0.684). Resistivity index values of the ophthalmic and central retinal arteries with ganglion cell complex thickness correlated significantly. On the other hand, no significant relationship for retinal nerve fiber layer thickness was identified.
conclusionsStructural changes (ganglion cell complex and ganglion cell inner plexiform layer) in patients with pseudoexfoliation glaucoma and early glaucomatous loss showed a significant correlation with changes in ocular vascular hemodynamics. In cases where systemic vascular resistance is increased, ganglion cell complex and ganglion cell inner plexiform layer may not exactly reflect glaucoma state. In such cases, thickness changes in the retinal nerve fiber layer may give more realistic results regarding glaucoma. We have seen that pseudoexfoliation glaucoma-induced structural deterioration and increased resistance in ocular hemodynamics correlated with ganglion cell complex, but not retinal nerve fiber layer.
