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 explore current delays in diagnosis of retinoblastoma (Rb) and effect on outcome with comparison to a study from the 1990s.

settingPrimary, secondary, tertiary care: majority from South of England.

participantsA retrospective analysis of 93 new referrals of sporadic (non-familial) Rb to a specialist Rb unit in London, UK from January 2006 to February 2014. PRIMARY AND SECONDARY OUTCOMES: International Intraocular Retinoblastoma Classification, lag times including parental delay and healthcare professional delay, patients requiring enucleation and requirement of adjuvant chemotherapy postenucleation (high-risk Rb).

resultsDuring the study period, 29% presented via accident and emergency (A&E). The median referral time from symptom onset to visiting primary care (PC) was 28 days and PC to ophthalmologist 3 days (range 0-181 days). The median time from local ophthalmologist to the Rb Unit was 6 days (0-33). No significant correlation was found between delay and International Classification of Retinoblastoma grade (p>0.05) or between postenucleation adjuvant chemotherapy and enucleation groups (p>0.05). Less enucleations (60%) are being performed compared with the previous study (81%) (p=0.0015).

conclusionsParents are attending A&E more compared with the 1990s and this may reflect the effect of public awareness campaigns. More eyes are being salvaged despite a similar number of children requiring adjuvant chemotherapy. High-risk Rb and Group E eyes do not correlate with increased lag time in the UK. Other determinants such as tumour biology may be more relevant.
