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

backgroundTo identify factors and problems influencing treatment adherence in patients undergoing anti-VEGF therapy for neovascular age-related macular degeneration (AMD) under real-life conditions.

methodsCross-sectional study was conducted of 95 patients receiving ranibizumab therapy on a pro re nata (PRN) regimen with monthly controls in a tertiary health care clinic. Monthly controls included best corrected visual acuity, slit-lamp examination and spectral-domain optical coherence tomography. Adherence was measured using Kaplan-Meier time-to-discontinuation analysis. Patients were asked to respond to a 16-item questionnaire covering items such as anxiety, subjective benefit, and financial issues of therapy.

resultsForty-two men and 53 women were included. After a mean follow-up time of 675 days (range 63-1008), adherence was 81.1% (77/95). The mean number of follow-up visits was 19 (3-30), the mean number of intravitreal injections was ten (3-23). Seven patients withdrew from treatment due to subjective dissatisfaction with benefit. Other reasons for loss to follow-up were death in one case, serious general disease in three patients, and treatment options closer to home in five cases. Two patients cancelled further follow-up after treatment cessation due to terminal fibrosis. 62.1% of patients were afraid of a negative examination result, whereas 19.0% were afraid of intravitreal injections. A major problem was travel to and from the hospital (46.3%), with 61.5% of patients requiring escort.

conclusionDespite necessary monthly visits, patients showed a high adherence to therapy. The major problem was travel to and from the hospital. From the patients' point of view, anxiety of a negative examination result was more pronounced than fear of intraocular injections, which would be an argument for continuous injections rather than for a PRN regimen.
