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

Neuroblastoma (NB) is the most common and deadly solid tumor in children. The majority of NB patients have advanced stage disease with poor prognosis, so more effective, less toxic therapy is needed. We developed a novel nanocarrier-based strategy for tumor-targeted delivery of a prodrug of SN38, the active metabolite of irinotecan. We formulated ultrasmall-sized (<100 nm) biodegradable poly(lactide)-poly(ethylene glycol) based nanoparticles (NPs) containing SN38 conjugated to tocopherol succinate (SN38-TS). Alternative dosing schedules of SN38-TS NPs were compared to irinotecan. Comparison of SN38-TS NPs (2 doses) with irinotecan (20 doses) showed equivalent efficacy but no cures. Comparison of SN38-TS NPs (8, 8, and 16 doses, respectively) to irinotecan (40 doses) showed that all SN38-TS NP regimens were far superior to irinotecan, and "cures" were obtained in all NP arms. SN38-TS NP delivery resulted in 200× the amount of SN38 in NB tumors at 4 hr post-treatment, compared to SN38 detected for the irinotecan arm; no toxicity was seen with NPs. We conclude that this SN38-TS NP formulation improved delivery, retention, and efficacy, without causing systemic toxicity.
