A higher frequency of lumbar ossification of the posterior longitudinal ligament in elderly in an outpatient clinic in Japan.
Article in International journal of general medicine, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
purposeLittle is known about the prevalence and epidemiological characteristics of lumbar ossification of the posterior longitudinal ligament (OPLL). We analyzed the rate of lumbar OPLL in an outpatient unit where primary care physicians are working in Japan, to better understand the epidemiological characteristics of the disease.
methodsWe analyzed consecutive, first-time visiting outpatients who received abdominal and pelvic computed tomography (CT) scan at the Department of General Medicine, Asahikawa Medical University Hospital, Japan, between April 2009 and March 2012. Each parameter such as age, sex, and clinical presentation was investigated.
resultsOut of 393 patients who underwent abdominal and pelvic CT scan, 33 (8.4%) were diagnosed as lumbar OPLL. When compared with patients without lumbar OPLL (n = 360), there was no significant difference in gender, body mass index (BMI), presence of hypertension, diabetes mellitus or hyperlipidemia, and smoking habit, while the age in patients with lumbar OPLL was significantly higher.
conclusionThese results suggest for the first time that lumbar OPLL is frequently observed in elderly people in the primary care setting, in Japan.
