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

BACKGROUND/

aimsLittle is known about the efficacy of low-dose transdermal fentanyl (TDF) patches in opioid-naïve patients with moderate-to-severe cancer pain.

methodsThis study had an open-label, prospective design, and was conducted between April 2007 and February 2009 in seven tertiary cancer hospitals; 98 patients were enrolled. TDF was started using a low-dose formulation (12.5 µg/hr), and the dose was adjusted according to the clinical situation of individual patients. Pain intensity, the TDF doses used, and adverse events (AEs) were monitored over 4 weeks. Data were analyzed using the intent-to-treat and per-protocol principles.

resultsOf the 98 patients enrolled, 64 (65%) completed the study. The median pain intensity decreased from 6.0 to 3.0 (p < 0.001) at the follow-up visit. The efficacy of low-dose TDF on pain relief was consistent across groups separated according to gender (p < 0.001), age (p < 0.001), metastasis (p < 0.001), previous treatment (p < 0.001), and baseline pain intensity (p < 0.001). The decrease in pain intensity was significantly greater in the severe group compared with the moderate group (mean ± SD, 5.10 ± 2.48 vs. 2.48 ± 1.56; p < 0.001). TDF dose (27.8 µg/hr vs. 24.8 µg/hr, p = 0.423) and the mean treatment time (7.5 days vs. 7.9 days, p = 0.740) required for pain control were not different between the two pain-intensity groups. Patients had AEs of only mild or moderate intensity; among these, nausea (38%) was the most common, followed by vomiting (22%) and somnolence (22%).

conclusionsLow-dose TDF was an effective treatment for patients with cancer pain of moderate-to-severe intensity. Further randomized trials assessing the efficacy of TDF for severe pain and/or optimal starting doses are warranted.
