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

Purpose: Few patients scattered among centers complicate investigation of thrombotic thrombocytopenic purpura (TTP) and Evans syndrome (ES). Routinely collected Danish register data captures the total population and includes lifelong follow-up. We aimed to validate registered TTP and ES diagnoses and to explore clinical characteristics. Patients and Methods: We identified all patients in Denmark with diagnosis registrations indicative of TTP or ES in the Danish National Patient Registry 2000-2019, validated diagnoses through medical record review, and extracted and presented data on initial treatment and complications. Results: Diagnoses for patients registered with TTP and ES were confirmed for 46% and 59%, respectively. Among validated TTP patients the most widespread complications at time of diagnosis were neurological symptoms or deficits, observed in 81% of cases. Other frequent types of complications in TTP patients were any organ failure (32%) and infection (25%). Initial management and complications did not change for patients diagnosed between 2000 and 2009 and 2010 and 2019, and survival remained constant (overall mortality 26%, median follow up of 8.4 years). Treatments and complications also remained unchanged for ES patients. Conclusion: Overall, diagnostic accuracy, complications and prognosis have remained relatively constant for patients over the study period. These now validated cohorts of Danish TTP and ES patients will be utilized in future studies to examine long-term health outcomes.
