1 · What the graph read from it

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.

2 · The registry

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

purposeTo demonstrate the capabilities of single-shot widefield swept-source OCT angiography (SS-OCTA) in detecting subclinical retinal neovascularization (RNV), quantifying nonperfusion areas (NPAs), and exploring the relations between NPAs and subclinical RNV in eyes graded as nonproliferative diabetic retinopathy (NPDR).

methodsEyes clinically graded as moderate to severe NPDR underwent SS-OCTA imaging. Expert graders identified subclinical RNV, defined as vessels with a flow signal above the internal limiting membrane on OCTA that are not visible on dilated fundus examination. This identification was based on a combination of en face OCT, en face OCTA, and cross-sectional OCTA overlaid on OCT. NPA index was calculated as a percentage of automatically quantified NPA over the area in the posterior pole, the mid-periphery, and the total imaged area.

resultsTotally 37 eyes, including 21 had severe NPDR and 16 had moderate NPDR. Subclinical RNV was present in 14 eyes (37.8%). The eyes with RNV had significantly higher mid-peripheral and total NPA indices but not in the posterior region (mid-peripheral NPA: 31.97% ± 7.02% vs. 24.80% ± 6.60%, p = 0.041; total NPA: 27.96% ± 6.36% vs. 21.61% ± 5.65%, p = 0.046; all values are reported as mean ± standard deviation). The total NPA index showed the highest diagnostic accuracy for subclinical RNV detection (AUC: 0.761; 95% CI, 0.592-929, with a sensitivity of 64.3% and a specificity of 87% at a cutoff value of 28.84%).

conclusionWidefield SS-OCTA can detect subclinical RNV. The eyes with higher mid-peripheral NPA indices are more likely to have subclinical RNV, indicating that the NPA index may be a useful biomarker for identifying eyes at risk of RNV.
