Real-World Outcomes of Allogeneic Immunosafe Plasma Rich in Growth Factors Eye Drops for Refractory Ocular Surface Diseases: A Prospective Observational Study.

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
introductionImmunosafe plasma rich in growth factors eye drops (is-ePRGF) have shown anti-inflammatory and regenerative effects on ocular surface diseases (OSD). However, medical or technical issues may preclude some patients from undergoing autologous blood extraction. We aimed to evaluate the safety and clinical outcomes of allogeneic is-ePRGF therapy for refractory OSD in real-world practice.
methodsA single-center cohort was conducted involving consecutive patients with severe OSD nonresponsive to conventional therapy. All participants received allogeneic is-ePRGF derived from healthy family donors as compassionate treatment (one drop four times daily for 6 weeks per cycle), with a minimum follow-up of 3 months. Primary outcomes included symptom changes assessed by Ocular Surface Disease Index (OSDI) and Symptom Assessment iN Dry Eye (SANDE) questionnaires, resolution of persistent epithelial defects (PED), and adverse events (AE). Secondary outcomes included best-corrected visual acuity (BCVA), intraocular pressure (IOP), corneal staining, Schirmer I test, tear break-up time (BUT), conjunctival bulbar redness, and meibomian gland dysfunction (MGD). Multilevel mixed-effects models were used to account for intra-patient and inter-eye correlations.
resultsA total of 30 patients (58 eyes; mean age 53.4 ± 22.6 years; 50% female) were included. The most common diagnoses were severe dry eye disease and neurotrophic keratopathy, frequently associated with autoimmune/inflammatory conditions. Overall, 12 patients (40%) had previously received autologous therapies. Donors were primarily first-degree relatives. Median follow-up was 9 months (range 3‒30 months), with a mean of 6.2 ± 3 cycles. OSDI and SANDE scores significantly improved (p < 0.001). Among 12 cases with PED, 8 (67%) fully resolved. No AE occurred. BCVA (p = 0.010), Schirmer test, BUT, conjunctival bulbar redness, corneal staining, and MGD severity improved significantly (p < 0.001); IOP remained stable (p = 0.132).
conclusionsAllogeneic is-ePRGF was a safe and effective alternative for refractory OSD when autologous sources were not available or suitable. Standardization of regulatory frameworks for allogeneic blood-based therapies is needed to support broader clinical adoption.
