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

To explore the difference in foveal microvascular features using optical coherence tomography angiography (OCTA) between basic intermittent exotropia (IXT) and age-matched controls to observe IXT progression by fundus examination. Recruitment to the analyse and data analysis occurred from August 2021 to June 2022. Participants aged 7 to 17 years old including IXT and age-matched controls were divided into two groups, IXT and control group from clinic in the First Affiliated Hospital of Soochow University (n = 74). All participants undergo basic opthalmologic examination and OCTA scan. The parameters including various regions of retinal thickness (RT), the macular density of deep capillary plexus (DCP), superficial capillary plexus (SCP), and foveal avascular zone (FAZ). A total of 35 (70 eyes) IXTs, and 39 (39 eyes) controls were enrolled. Compared with controls, macular and inferior RT was thicker in IXT groups (p > 0.05). IXT patients were divided into moderate (20∆ < PD ≤ 40∆) and large (40∆ < PD ≤ 60∆) angles of deviation groups. The SCP and DCP were not significantly thinner in deviated eyes than those in dominant eyes and controls.(p > 0.05) No difference was found in various angles of deviation groups in any OCTA parameters. Compared with controls, no alterations in microvascular features were investigated in basic IXT using OCTA. The angles of deviation may not promote macular perfusion. The specific role of macular density in the diagnosis, management, and pathogenesis of IXT is unclear, further analyses may yield to be performed.
