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 evaluate the utility of intraoperative optical coherence tomography (OCT) in filtration surgery using PRESERFLO STUDY

designSingle-center prospective observational study

methodsFiltration surgery using the MicroShunt was performed on 14 patients (15 eyes) diagnosed with open-angle glaucoma at our institution. The insertion pathway was created using a knife under intraoperative OCT guidance, and the position of the MicroShunt was verified after insertion. In cases of inadequate positioning, a new insertion pathway was created. Furthermore, the correct position was confirmed postoperatively using anterior segment OCT.

resultsIn all cases, the real-time observation or replay playback of intraoperative OCT allowed for the visualization of the positional relationship between the device and surrounding tissues. This provided valuable assistance in determining the adequacy of the insertion pathway. In certain cases, the knife or inserted MicroShunt was in contact with the cornea or iris, leading to a revision of the insertion pathway. Regardless of the case, at the end of each surgery confirmation was made that the inserted MicroShunt was fixed in the proper position in the anterior chamber. Postoperative anterior segment OCT also revealed its presence in a similar position.

conclusionIntraoperative OCT is a valuable tool for ensuring a more secure insertion in filtration surgery using MicroShunt.
