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

introductionBecause of deteriorating exocrine function, malabsorption renders chronic pancreatitis (CP) patients at risk of osteoporosis and fracture. However, the pathogenesis of low bone mineral density (BMD) has not been characterized. We hypothesized that bone turnover is elevated in CP, and we sought to investigate an association between bone metabolism and systemic inflammation.

methodsTwenty-nine CP patients and twenty-nine matched controls were recruited. Bone-turnover markers procollagen 1 amino-terminal propeptide (P1NP), OC (osteocalcin; bone formation markers), and carboxy-terminal telopeptide of type I collagen (CTX-I; bone resorption marker) were measured along with vitamin D (25-hydroxyvitamin D, 25OHD), parathyroid hormone (PTH), interleukin 6 (IL-6), high-sensitivity (hs) C-reactive protein (CRP), and sex/thyroid hormones. BMD was measured by dual-energy X-ray absorptiometry. Smoking status was noted.

resultsOf the CP patients, 31% had osteoporosis and 44.8% osteopenia (controls: 6.9 and 51.7%, respectively; P=0.019). BMD was lower for patients at the lumbar spine (P=0.014) and femoral neck (P=0.029). Patients had elevated bone formation (P1NP (P=0.0068), OC (P=0.033)) and bone resportion (CTX-I (P=0.016)) compared with controls. Patients had lower 25OHD compared with controls (P=0.0126) and higher inflammatory markers (hsCRP, P=0.0013). Sex and thyroid hormone levels were similar. Patients with lowest 25OHD levels had highest P1NP. In a multivariable model, age, PTH, and smoking were predictive of 25OHD. Patients with osteoporosis had higher P1NP, PTH, and IL-6 and lower 25OHD. Using analysis of variance, inflammation (hsCRP) was highest in those with lowest 25OHD and lowest BMD.

conclusionsFor the first time, bone turnover was shown to be abnormal in CP, and importantly, an association between low 25-OHD, smoking, and systematic inflammation was identified. Moreover, those with osteoporosis had the highest systemic inflammation. Together these factors provide an avenue for potential modification of risk factors, which may ultimately reduce bone loss and avert fractures in this group.
