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

backgroundMore invasive retinoblastoma, characterized by increased morbidity and mortality, with lower rates of eye salvage and higher rates of extraocular dissemination, seems more prevalent in resource-poor countries. The relationship of diagnostic delay (lag time) and sociodemographic factors on the extent of disease at diagnosis has not been examined separately for unilateral and bilateral retinoblastoma.

methodsAt diagnosis, consenting parents of 179 Mexican children with retinoblastoma were interviewed about initial symptoms and household demographic characteristics. Clinical presentation was classified using St. Jude's, International Staging System (ISS), and International Intraocular Retinoblastoma Classification (IIRC) criteria. Lag time (delay between noting symptoms and diagnosis) and sociodemographic factors were examined as predictors for higher stage at diagnosis and overall survival (OS).

resultsIn bilateral disease, lag time predicts stage at diagnosis using St. Jude's, and ISS criteria (P < 0.005 in multivariate regression), and OS (P < 0.05, Cox hazards), but not extent of intraocular disease (by IIRC). In unilateral disease, lag time predicts neither extent of disease (using ISS, St Jude's, and IIRC), nor OS. Indicators of prenatal poverty, including lower maternal education and the presence of dirt flooring in the home, predict more advanced disease by IIRC for bilateral retinoblastoma, and for unilateral by ISS, and St Jude's (P < 0.001) as well as OS (P < 0.05).

conclusionThese results suggest unilateral and bilateral retinoblastoma differs in factors governing progression and extraretinal extension, possibly reflecting underlying biologic heterogeneity. IMPACT: This demonstrates differing effect of social factors on extent of intra- and extraocular disease depending on laterality with implications for screening strategies.
