A Survey on Patients' Opinions of Alternative Drug Delivery Systems for the Treatment of Glaucoma in South-South Nigeria.
Article in Middle East African journal of ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
purposeDespite the human ocular surface being easily accessible, ocular drug delivery can be challenging. When applied improperly, topical medications, the most popular first-line treatment used to treat glaucoma, can have a very brief contact time with the ocular surface and may not have the desired therapeutic impact. Drug delivery devices are gadgets that can address some of these problems. This study aims to determine patients' opinions on ocular drug delivery devices used in the treatment of primary open-angle glaucoma (POAG).
methodsA pretested interviewer-administered questionnaire was used in a cross-sectional study of 115 POAG patients recruited from outpatient clinics in two Nigerian tertiary health institutions. Participants were asked about their understanding and acceptance of five Ocular drug delivery systems (ODD), namely drug-emitting contact lenses (CL), punctual plugs, subconjunctival injections, intracameral implants, and trabecular meshwork micro-stents, for the treatment of POAG.
resultsSixty (52.2%) participants, whose average age was 50 ± 9.8 years, were men. Self-pay was used for eye health treatments by 65% of participants. Of the participants, 68.7% admitted to using eye drops on their own. 57% of people were said to take their glaucoma medications consistently. CL and subconjunctival implants were seen to be most acceptable according to 39% and 30% of participants, respectively. Major factors determining the acceptability of ODD for POAG treatment were observed to be cost and effectiveness.
conclusionPatients in our cohort who are being treated for POAG have a fairly positive attitude towards ODD. The prospective use of these devices for POAG treatment in Nigeria will depend on their efficacy and cost, as well as how ophthalmologists will weigh ODD options.
