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

Background: Primary biliary cholangitis (PBC) is a rare, chronic autoimmune, cholestatic liver disease affecting approximately 318 per million Canadians. There is limited information regarding the characterization of this patient population in Canada. Consequently, we aim to describe a cohort of PBC patients managed across liver centres serving this type of population. Methods: A cross-sectional examination of 1,125 PBC patient charts at 15 liver centres across Canada was conducted between January 2016 and September 2017. Results: Data from 1,125 eligible patients were collected from 7 Canadian provinces. The patient population was largely female (90.2%), had a median overall age of 61.3 years, and a median overall time since diagnosis of 6.4 years. Of the patients included in the study, 89% were on ursodeoxycholic acid (UDCA) therapy at a median dose of 14.0 mg/kg/day and 4.4% were previously treated with UDCA, whereas 6.6% were never treated with UDCA. Of the patients with available data (n = 1067), 289 (27.1%) presented with alkaline phosphatase (ALP) levels ≥200 IU/L and/or total bilirubin levels ≥21 µmol/L. Assessment of UDCA treatment response revealed that 26.6% and 38.3% of patients were inadequate responders according to the Toronto and Paris-II criteria, respectively. Mortality occurred in 1.2% (14) of patients, with liver-related adverse outcomes being more commonly observed in patients who discontinued UDCA compared to those who are currently on treatment (36.3% and 19.6%, respectively). Conclusion: This study showed that Canadian PBC patients present with demographics and features commonly reported in the literature for this disease. Over one third of PBC patients had inadequate response to UDCA treatment or were not currently being treated with UDCA. Consequently, there is a significant unmet therapeutic need in this Canadian PBC population.
