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
purposeIn eyes with intermediate age-related macular degeneration (iAMD), we separately quantified the hyperreflective foci (HRF) along the retinal pigment epithelium (rpeHRF) and the intraretinal HRF (iHRF) to determine if the location of the HRF predicted the progression from iAMD to the onset of large persistent choroidal hypertransmission defects (hyperTDs).
designPost hoc subgroup cohort analysis of a prospective study.
methodsA retrospective analysis was performed on a prospective natural history database of eyes with AMD imaged using swept-source optical coherence tomography (SS-OCT). En face images derived from choroidal slabs positioned 64 to 400 µm beneath Bruch membrane were used with a semiautomated algorithm to identify and quantify hypotransmission defects (hypoTDs) attributable to either iHRF or rpeHRF within a 5-mm fovea-centered circle. iHRF were identified on corresponding B-scans as hyperreflective lesions within the neurosensory retina, and rpeHRF were identified as areas of retinal pigment epithelium thickening. Multivariable survival analysis was performed to determine if the area measurements of either iHRF or rpeHRF were more likely to predict the onset of the first large persistent hyperTD.
resultsOf the 171 eyes with iAMD included in this study, 82 (48%) developed at least 1 large hyperTD during a median follow-up of 59.1 months. Univariable Cox regression analyses showed that rpeHRF area (P < .001), iHRF area (P = .003), and drusen volume (P < .001) were all significantly associated with the onset of the first large persistent hyperTD. However, a multivariable Cox regression model showed that only the rpeHRF area remained a significant predictor of disease progression (P < .001).
conclusionsIn iAMD eyes, the area of rpeHRF was more predictive of disease progression than either the drusen volume or iHRF, which suggests that these rpeHRF serve as harbingers of focal atrophy formation and may predict where hyperTDs form.
