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

purposeTo describe the clinical outcomes of combined prolene gonioscopy assisted transluminal trabeculotomy (GATT) with phacoemulsification in patients with open-angle glaucoma.

methodsRetrospective study of patients with cataract and open-angle glaucoma treated with GATT and phacoemulsification with intraocular lens (IOL) implantation. Patients with neovascular glaucoma, corneal decompensation, unstable IOL, and with bleeding disorders were excluded. The cumulative probability of failure was the primary outcome. Secondary outcomes were the complete success rate, the mean change on intraocular pressure (IOP), best-corrected visual acuity (BCVA) and number of glaucoma medications at the last follow-up. The frequency of complications was also recorded.

resultsThirty two eyes (25 patients) were included. Nineteen (59.3%) were females, with a mean age of 73.4±12.4 (23-87 years) and a mean baseline BCVA of 1.1±0.75 (0.3-3) LogMAR units. The cumulative probability of failure was 3.2% at 1 month and 6.3% at 6 and 12 months. Sixty-eight and 65.5% of eyes achieved complete success at 3 and 6 months, respectively. The reduction of IOP and number of glaucoma medications at 6 months were statistically significant (p<0.0001 and p=0.0002, respectively). There was a statistically significant improvement of BCVA (from 1.1±0.7 to 0.4±0.7) at 6 months (p<0.0001). IOP spikes (18.7%) and transient hyphema (9.3%) were the most common complications.

conclusionCombined GATT with cataract surgery reduced the IOP and was associated with low failure rates and few ocular complications. This procedure offers the advantage to avoid the need for a bleb, scleral, or conjunctival incision, allowing the possibility for future glaucoma procedures.
