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
purposeTo report a new spectral domain optical coherence tomography (OCT) finding called the pigtail sign. It was found during follow-up of idiopathic macular hole cases after inverted internal limiting membrane (ILM) flap surgery.
methodsThis is a retrospective case series of 12 eyes (12 patients) who underwent inverted ILM flap technique for idiopathic macular hole closure. Spectral domain optical coherence tomography images were analyzed for the presence of this new finding.
resultsA new spectral domain OCT finding of a curved coiled line hanging above the surface of the retinal layers was seen in all patients. The mean preoperative best corrected visual acuity (BCVA) logMAR value was 1.25 ± 0.11. At the 6-month follow-up visit, the mean LogMAR BCVA was 0.35 ± 0.18. All the cases showed macular hole closure after surgery.
conclusionThis new spectral domain OCT sign can be seen in some OCT scans during follow-up of idiopathic macular hole cases after inverted ILM flap surgery.
