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

purposeThe inverted internal limiting membrane (ILM) technique was recently introduced for refractory macular hole. Here, we evaluate a case of macular pucker formation after macular hole surgery using the inverted ILM flap technique and silicone oil tamponade. After undergoing vitrectomy combined with ILM removal, the patient had a good visual prognosis. OBSERVATIONS: A 49-year-old male with macular hole affecting both of his eyes underwent vitrectomies. Three months after the first surgery in his right eye, macular pucker formation was observed in the macula, which was associated with the ILM flap used to cover the macular hole. After peeling the ILM, the macula returned to a normal contour and visual acuity improved. Examination of the removed ILM revealed macrophage-like cells containing silicone oil particles that were responsible for the ILM contraction. CONCLUSIONS AND IMPORTANCE: When using the inverted ILM flap technique and silicone oil, macular pucker may occur after macular hole surgery. Peeling of the ILM flap restored the macular shape and did not reopen the macular hole, thereby improving visual acuity. Thus, silicone oil should be used with caution when performing macular hole surgery with the ILM flap technique.
