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

BACKGROUND/

objectivesTo explore the attitudes of UK glaucoma specialists regarding the current and future practice of trabeculectomy and the novel PRESERFLO™ MicroShunt (PF-MS) device, and intentions to adopt the PF-MS into routine glaucoma surgical practice.

methodsOnline survey of UK and Éire Glaucoma Society members.

results43 glaucoma consultants completed the survey. All surgeons performed trabeculectomies (median of 40 annually) and 51% undertook PF-MS procedures (median of 22.5 annually). The mean duration of surgery was reported as 48.9 (SD 13.3) and 31.2 (SD 9.9) min for trabeculectomy and PF-MS respectively (p < 0.0001). For surgeons not currently using the PF-MS, 65% planned to do so. Respondents judged completion of 35 trabeculectomies and 10 PF-MS were required to achieve basic competence. 91% of participants predicted their trabeculectomy volume would decrease and 73% expected PF-MS usage to increase. Respondents reported a median of six and four follow-ups within 3 months post surgery for trabeculectomy and PF-MS respectively (p < 0.0001). Respondents reported trabeculectomy required more post-operative interventions than the PF-MS and 81.8% judged the patient experience to be better with the PF-MS. The PF-MS was deemed suitable for early visual field loss by 72% of respondents, severe visual field loss by 35% and normal tension glaucoma by 21%.

conclusionThe PF-MS has seen rapid adoption in the UK. Respondents predict its usage will significantly increase whilst trabeculectomies will decrease. They report the PF-MS is quicker to learn and perform, and requires less post-operative follow-ups and interventions which may facilitate a more efficient service delivery for patients requiring glaucoma surgery.
