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

purposeThis study aimed to compare the effect of trabectome surgery in patients with and without intolerance to their medication and with preoperatively sufficiently controlled, insufficiently controlled, and uncontrolled intraocular pressure (IOP) on the surgical outcome. PATIENTS AND

methodsA total of 155 eyes (133 patients) with different forms of open angle glaucoma with or without intolerance to their glaucoma medication undergoing trabectome surgery alone (AIT) or combined with phacoemulsification (phaco-AIT) were included in this retrospective monocentric study. Patients were corresponding to IOP ≤ 18 mmHg (controlled but glaucoma progression or intolerance, group 1), 19-26 mmHg (insufficiently controlled, group 2), and ≥ 26 mmHg (not controlled, group 3), respectively. Pre- and postoperative IOP and the number of IOP-lowering medications were registered over 12 months. Surgical success was defined as a postoperative IOP of ≤18mmHg and/or reduction of the topical treatment demand after 1 year.

resultsOf the 155 included eyes, 79 received AIT and 76 received phaco-AIT. Sixty-nine eyes had a preoperatively sufficiently controlled IOP, 63 had an insufficiently controlled IOP, and 23 had an uncontrolled IOP. In all groups, the IOP significantly dropped by 6 and 12 months after surgery (

conclusionIndependently of the preoperative IOP, a satisfying surgical success was achieved using AIT. In instances that do not qualify for filtrating surgery, trabectome surgery alone or in combination with phacoemulsification thus represents a safe and effective minimally invasive glaucoma surgery technique regardless of an intolerance to the topical medication.
