Optical Coherence Tomography Biomarkers Predict the Long-Term Restorative Effect of Early Anti-VEGF Treatment on Diabetic Macular Edema.

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
background/purposeThis study compared the effects of three induction doses of anti-vascular endothelial growth factor (anti-VEGF) on diabetic macular edema (DME) with that of long-term treatment using biomarkers to find out the predictability potential of early response to anti-VEGF treatment for the long-term restorative effect.
methodsWe retrospectively reviewed the clinical and optical coherence tomography (OCT) data of 71 DME eyes treated with three monthly anti-VEGF doses and followed for 1 year. BCVA, central subfield thickness (CST), subretinal fluid (SRF), intraretinal cysts, hyperreflective foci (HF), disorganization of inner retinal layers (DRILs), ellipsoid zone/external limiting membrane (EZ/ELM) integrity, and vitreoretinal relationships were assessed at baseline, 3, 6, and 12 months.
resultsPatients (50.7% male) had a mean follow-up of 12 months. After three anti-VEGF doses, 19 eyes required no additional injections, 25 continued anti-VEGF, 20 switched to dexamethasone implants, and seven received combination therapy. Best corrected visual acuity (BCVA) improved from 0.52 to 0.40 logMAR at 3 months, 0.30 at 6 months, and stabilized at 0.40 at 12 months. CST decreased from 406 µm to 317 µm at 3 months and 307 µm at 12 months. Significant early improvements in BCVA, CST, SRF, and intraretinal cysts were sustained in the long-term follow-up. HF reduction became significant after 6 months, while DRIL and EZ/ELM integrity remained unchanged.
conclusionsThe improvement of OCT biomarkers in DME patients supported that intravitreal anti-VEGF significantly restored the retinal microstructure, which was already evident at 3 months in the control after anti-VEGF induction.
