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

purposeWe present an ab interno removal technique combined with a needling procedure for a malpositioned Ex-PRESS glaucoma shunt. STUDY

designRetrospective case series.

methodsThis study examined four cases of malpositioned Ex-PRESS shunts. Needle bleb revision was performed to expand the space under the scleral flap and bleb area. Clinical data, including corneal endothelial cell density (ECD), intraocular pressure (IOP), and anterior segment optical coherence tomography images (AS-OCT), were retrieved from clinical records.

resultsAll four cases underwent ab interno shunt removal combined with needle bleb revision without any serious complications. In three cases of anterior shunt malposition, a reduction in ECD was apparent before surgery but remained relatively stable after surgery. In one patient with posterior shunt malposition, shunt occlusion was suspected before surgery, but bleb formation and IOP improved after surgery. IOP was 8 mmHg to 21 mmHg (median, 10.5 mmHg) before surgery and 5 mmHg to 17 mmHg (median, 10 mmHg) 12 months after surgery. No additional glaucoma surgery was required within the first 12 months; however, after 12 months, two patients required additional glaucoma surgery.

conclusionAb interno Ex-PRESS device removal combined with bleb needling is an important procedure in patients with malpositioned Ex-PRESS devices.
