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

aimTo assess the refractive outcomes and effect of the macular status in eyes with proliferative diabetic retinopathy (PDR) and significant vitreous hemorrhage received with combined phacoemulsification and pars plana vitrectomy (phacovitrectomy).

methodsThis retrospective case-control study recruited 176 eyes, including 86 PDR eyes with severe vitreous hemorrhage, who received phacovitrectomy with intraocular lens implantation, and 90 eyes who underwent phacoemulsification only for cataracts (control group). Postoperative follow-up visits documented best-corrected visual acuity (BCVA) and refractive outcomes at each examination. Postoperative refractive outcomes were quantified as spherical equivalents. The primary outcome measure was the refractive prediction error (PE). The PE and absolute prediction error (AE) were employed as key metrics. Additionally, the number and percentage of patients achieving refractions within ±0.25 diopters (D), ±0.50 D, ±0.75 D, ±1.00 D, and ±2.00 D of the target refractive outcome were documented.

resultsThe overall mean age was 64.4±10.5y. There were 98 (55.7%) female and 78 (44.3%) male patients. In the PDR eyes with the phacovitrectomy surgery, mean PE (-0.008±0.872 D) and AE (0.662±0.563 D) by ultrasound biometry showed no statistically significant differences as compared to the control group (PE: 0.117±0.621 D,

conclusionCombined phacovitrectomy for PDR with severe vitreous hemorrhage exhibits no ultrasound biometry discrepancies as compared to those received phacoemulsification alone. However, the patients with macular thickening show a noticeable myopic shift.
