Risk factors for recurrent retinoblastoma after intravenous chemotherapy.
Article in International ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeTo analyze the risk factors and estimate the risk period for tumor recurrence in intraocular retinoblastoma (RB).
methodsRetrospective study of 60 RB patients.
resultsThe mean age at presentation with RB was 16 months (median 11 months; range 1-84 months). Tumor was unilateral in 13 (22%) and bilateral in 47 (78%) patients. Of 83 eyes with intraocular RB, group B (n = 27; 33%) tumors were more common based on International Classification of Intraocular Retinoblastoma. All cases received intravenous chemotherapy as a primary treatment. Over a mean follow-up period of 57 months (median 38 months; range 12-185 months) post-primary treatment, 44 (73%) patients developed tumor recurrence. The mean interval between the completion of primary treatment and first tumor recurrence was 5 months (median 3 months; range 1-24 months). The total duration of treatment for complete tumor control including treatment of tumor recurrences was 20 months (median 19 months; 2-58 months). By multivariate analysis, the factors predictive of tumor recurrence were multiple tumors (p = 0.008) and retinal detachment (p = 0.003) at presentation. Kaplan-Meier estimate of tumor recurrence at 6 months, 1 year, 3 years, and 5 years was 20%, 31%, 68%, and 73%, respectively. There was no tumor recurrence beyond 5 years since primary treatment.
conclusionMultiple tumors and retinal detachment at presentation are risk factors for tumor recurrence in RB. Close follow-up is mandatory for at least 5 years since the initiation of treatment for RB.
