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
Tube exposure is a recognised complication of glaucoma drainage devices (GDD). We report a case of successful repair of GDD tube exposure using a corneal patch graft and double-layer amniotic membrane in a visually precious eye with previous multiple surgeries. A 47-year-old man with juvenile open-angle glaucoma (JOAG) underwent trabeculectomy in both eyes (OU) and two GDD implantations in the right eye (OD). The left eye (OS) trabeculectomy failed, leading to panophthalmitis and evisceration. Six years after the second GDD in the OD, the superonasal tube became exposed (3.8 mm). Initial repair with an amniotic membrane transplant (AMT) failed, leaving the tube partially exposed (3.2 mm) with scarred, stiff conjunctiva but no leakage. Visual acuity (VA) was counting fingers, and intraocular pressure (IOP) was 11 mmHg. Conservative management included autologous serum eye drops, topical antibiotics, oral doxycycline, and a bandage contact lens. After six months, exposure was reduced to 1.0 mm but increased to 2.0 mm by month eight. The patient underwent surgical repair with a corneal patch graft and double-layer AMT. At six months postoperatively, the tube remained fully covered with no conjunctival erosion. Tube exposure is sight-threatening and may lead to endophthalmitis; persistent or recurrent cases can be effectively managed with corneal patch grafting combined with double-layer AMT, providing durable coverage, promoting re-epithelialisation, and allowing assessment of the underlying device.
