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

methodsLewis lung and prostate PC3 carcinoma-derived tumors were irradiated with regimens of 10 × 2 Gy, 6 × 4 Gy, 3 × 8 Gy or 2 × 12 Gy fractions. The tumor vasculature phenotype and function was evaluated by immunohistochemistry for endothelial cells (CD31), pericytes (desmin, α-SMA), hypoxia (pimonidazole) and perfusion (Hoechst 33342).

resultsRadiotherapy increased vascular coverage similarly in all fractionation regimens in both models. Vessel density appeared unaffected. In PC3 tumors, hypoxia was decreased and perfusion was enhanced in proportion with the dose per fraction. In LLC tumors, no functional changes were observed at

conclusionThe vascular microenvironment response of prostate and lung cancers to radiotherapy consists of both tumor/dose-independent vascular maturation and tumor-dependent functional parameters.
