Localization diagnosis of low back pain in a population-based study of a Japanese mountain village.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
purposeThe purposes of this study were to investigate 1) the location of low back pain (LBP) and 2) the relationships between the location of LBP and the LBP intensity or the quality of life (QoL) in a population-based study.
methodsThe location of LBP was categorized into four areas using palpation: midline of the lumbar region, paravertebral muscles, upper buttock, and sacroiliac joint. The extent of LBP in the situations/positions was assessed. The relationships between the location of LBP and the extent of LBP on the QoL were statistically analyzed.
results174 participants (average age: 72.3 years-old) were analyzed in this study. 93 participants (53.4% of the total) who had experienced LBP in the past three months were included in the LBP-positive group. Numerical rating scale (NRS) scores of the LBP-positive group were highest in the standing position. 51.6% of the LBP-positive group had LBP at the midline of the lumbar region, 40.9% at the paravertebral muscles, 28.0% at the upper buttock, and 15.1% at the sacroiliac joint. In the standing position, NRS scores of LBP at the upper buttock were significantly higher than those at the midline of the lumbar region and the paravertebral muscles (P<0.05). The Oswestry Disability Index scores of participants who had pain at the upper buttock were significantly higher than those at the midline of the lumbar region or paravertebral muscles (P<0.05).
conclusionOur study was the first report to investigate the location of LBP using palpation in a population-based study. LBP localization was significantly associated with LBP intensity and LBP-related QoL.
