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

purposeEndothelial dysfunction is a risk factor for osteonecrosis of femoral head (ONFH) and venous thromboembolism (VTE) [defined as deep venous thrombosis (DVT) or pulmonary embolism (PE)]. However, the risk of unprovoked VTE in non-traumatic ONFH patients remains unclear.

methodsWe investigated the relationship between ONFH and VTE using Taiwan National Health Insurance Research Database (NHIRD). Between 1997 and 2010, a total of 1514 non-traumatic ONFH patients were identified from 1,000,000 general populations after excluding initially concomitant diagnoses of DVT and PE, and subjects undergoing lower limb surgery within one year since enrollment. The comparison group (n = 15,140) without ONFH was set up by matching study cohort with age, gender, income and urbanization in a 1:10 ratio. Subjects diagnosed with VTE within one year after surgery were also excluded.

resultsThe patients with non-traumatic ONFH had significantly higher frequency of unprovoked VTE, including DVT, than general population (1.19 vs. 0.5%, p < 0.0007), whereas the frequency of PE was similar between these two groups (p = 0.4922). The cumulative incidence of VTE and DVT was also remarkably higher in the ONFH than non-ONFH group (all p < 0.001). After adjusting for age, gender, medications and comorbidities with multivariate analysis, the ONFH patients had a 2.3-fold increase in risk of DVT compared with non-ONFH counterparts (95% CI 1.28 to 4.13, p = 0.0053). Apart from ONFH, age > 65 years and hypertension were also identified as risk factors for DVT occurrence.

conclusionsThe incidence and risk of unprovoked VTE were significantly increased in the non-traumatic ONFH population.
