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

Pheophorbide a (Pba) is a chlorophyll catabolite that has been proposed as photosensitizer in photodynamic therapy. In a previous study we conjugated Pba to monomethoxy-polyethylene glycol (mPEG-Pba), to increase its solubility and pharmacokinetics. Here, we compare the photodynamic therapy efficacy of free Pba and mPEG-Pba to cure a subcutaneous amelanotic melanoma transplanted in C57/BL6 mice. The photosensitizers, i.p. injected (30 mg/kg), showed no toxicity when the animals were kept in the dark. But, after photoactivation with a 660 nm laser (fluence of 193 J/cm(2)), both photosensitizers, in particular mPEG-Pba, showed a strong efficacy to cure the tumor, both in terms of tumor growth delay and increase of Kaplan-Meier median survival time. Together, our in vivo data demonstrate that mPEG-conjugated Pba is a promising photosensitizer for the photodynamic therapy of cancer.
