Ketorolac, melatonin and latanoprost tri-loaded PLGA microspheres for neuroprotection in glaucoma.

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
Glaucoma is a multifactorial neurodegenerative disease that affects the retina and optic nerve. The aim of this work was to reach different therapeutics targets by co-encapsulating three neuroprotective substances with hypotensive (latanoprost), antioxidant (melatonin) and anti-inflammatory (ketorolac) activity in biodegradable poly (lactic-co-glycolic acid) (PLGA) microspheres (MSs) capable of releasing the drugs for months after intravitreal injection, avoiding the need for repeated administrations. Multi-loaded PLGA MSs were prepared using the oil-in-water emulsion solvent extraction-evaporation technique and physicochemically characterized. PLGA 85:15 was the polymer ratio selected for the selected formulation. Tri-loaded MSs including vitamin E as additive showed good tolerance in retinal pigment epithelium cells after 24 h exposure (>90% cell viability). The final formulation (KMLVE) resulted in 33.58 ± 5.44 µm particle size and drug content (µg/mg MSs) of 39.70 ± 5.89, 67.28 ± 4.17 and 7.51 ± 0.58 for melatonin, ketorolac and latanoprost respectively. KMLVE were able to release in a sustained manner the three drugs over 70 days. KMLVE were injected at 2 and 12 weeks in Long-Evans rats (n = 20) after the induction of chronic glaucoma. Ophthalmological tests were performed and compared to not treated glaucomatous (n = 45) and healthy (n = 17) animals. Treated glaucomatous rats reached the lowest intraocular pressure, enhanced functionality of bipolar and retinal ganglion cells and showed greater neuroretinal thickness by optical coherence tomography (
