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

objectivesTo investigate whether people with age-related macular degeneration (AMD) are able to self-detect symptoms and, if so, what symptoms they experience, from whom they first seek help, whether help is sought within the 1 week recommended by the Royal College of Ophthalmologists' guidelines and reasons for any delay. METHODS AND ANALYSIS: A retrospective, cross-sectional survey design. Postal surveys were sent to 4000 members of the UK Macular Society. Inclusion criteria were participants aged >50 years at diagnosis of AMD with diagnosis after August 2008; criteria were met by 621 respondents. The main outcome was reasons for delays in diagnosis for wet AMD. Data were analysed using χ

resultsOnly one third (n=199; 32%) of respondents were able to self-detect symptoms. In line with national guidance, over half (n=131; 64%) of those self-detecting symptoms sought help promptly. For those whose initial diagnosis was delayed more than 1 week, 27% had potentially treatable wet AMD requiring urgent treatment to prevent vision loss. Reasons for delay reflected individual & service-related issues, including AMD not being detected in the initial consultation, and individuals not perceiving the urgency for symptom investigation.

conclusionIn practice most patients sought help within 1 week; however, potentially sight-damaging delays occurred from symptom onset to diagnosis. Suggestions for reducing delay include increasing population awareness of AMD symptoms, the need for urgent detection and close monitoring for AMD and signposting patients to appropriate support services to ensure prompt detection of any future signs of wet AMD.
