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

Chronic low back pain (LBP) is a common condition and is generally treated using non-steroidal anti-inflammatory drug (NSAID); however, chronic NSAID use can decrease renal function. Tramadol, a weak opioid agonist, may improve chronic LBP and disability, while avoiding adverse effects such as gastrointestinal and renal toxicity. However, few studies have evaluated the short-term efficacy of opioids in Asian patients with chronic LBP. In this study, 24 patients with chronic LBP unresponsive to NSAIDs (10 men, 14 women; mean age, 65.1 ± 12.1 years) were prescribed tramadol/acetaminophen (37.5 mg/325 mg; four tablets daily) for 1 month. Then, the following parameters were assessed at baseline and after 1 week and 1 month of treatment: leg pain and LBP (Visual Analog Score [VAS]); activity of daily life (Roland-Morris Disability Questionnaire [RDQ]); and disability (Oswestry Disability Index [ODI]). Leg pain resolved within 1 week (p = 0.00093); however, LBP was relieved only at 1 month (p = 0.00034). The mean RDQ (p = 0.015) and ODI (p = 0.0032) scores were improved at 1 month. A total 41.6% of patients reported nausea and floating sensation beginning tramadol/acetaminophen treatment, and 12.5% (four patients) discontinued treatment as a result. LBP did not improve in 25% of patients administered tramadol/acetaminophen. Because this was an observational study, rather than a comparative study, further investigation is needed to evaluate the long-term efficacy of tramadol/acetaminophen in elderly patients with chronic LBP unresponsive to NSAIDs.
