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

Breakthrough cancer pain (BTcP) is a variegated phenomenon, that often presents in different ways in each individual, and may change its presentation in the same individual during the course of disease. An appropriate assessment is fundamental for depicting the pattern of BTcP in individuals. This information is determinant for a personalised management of BTcP. The use of opioids as needed, is recommended for the management of BTcP. There are several options which should be chosen according to the individual pattern of BTcP. In general, a drug with a short onset and offset should be preferred. Although oral opioids may still have specific indications, fentanyl products have been found to be more rapid and effective, providing analgesia in 5-15 min. The most controversial point regards the opioid dose to be used. The presence of tolerance suggests using a dose that is proportional to the dose used for background analgesia. In contrast, regulatory studies have suggested using the minimal available dose to be titrated until the effective dose. Further large studies should definitely settle this never-ending question.
