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

Because the brainstem has little functional redundancy, diffuse lesions have been regarded as inoperable. To determine whether local drug therapy can prolong survival in a rodent model of a tumor in such eloquent tissue, lethal doses of F98 and 9L tumor cells were injected into the brainstems of Fischer 344 rats. Five days after inoculations, 0.5 mg/ml solutions of carboplatin were infused at 1 microl/h for 7 days. Compared to control groups that survived 13-17 days with F98 tumors and 22-23 days with 9L tumors, animals locally infused with 0.1 mg of carboplatin survived 27-30 days (Prob > Chi Sq = 0.0003), and 32 days (Prob > Chi Sq = 0.01), respectively. Measurements of tissue platinum levels at autopsy suggested that infusions distributed pharmacologically relevant levels of carboplatin through a volume of tissue at least 0.5 cm in diameter. The results suggest that chronic low-flow infusions provide a promising approach to therapy for CNS lesions in tissues considered to be inoperable.
