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

introductionImmune thrombotic thrombocytopenic purpura (iTTP) is characterized by acute systemic microvascular thrombosis and is associated with a high morbidity and mortality, especially in delayed diagnosis (later than 6-7 days from symptoms). iTTP data in Brazil is scarce, so we aimed to characterize the clinical presentation and identify predictors of death risk in patients with this disease in Brazil.

methodsIn this single-center retrospective study the patients who underwent therapeutic plasma exchange (TPE) for presumptive or confirmed iTTP were evaluated regarding the epidemiological, clinical, laboratorial characteristics and management.

resultsA total of 50 patients (90 % female), with median age (IQR) of 34.1 (27-47) years, were enrolled, of which 12 (24 %) died. The most frequent symptoms were neurological (96 %), bleeding (76 %), gastrointestinal (52 %), fever (38 %), and cardiovascular (22 %). Neurological focal deficit and cardiovascular symptoms were more frequently observed in the non-survivor group (P = 0.0019 and P = 0.007, respectively). The mean ± SD number of days from beginning of symptoms to first TPE was 12.22 ± 7.91. We identified an association regarding mortality rate with a score MITS ≥ 2 points (P = 0.04), a higher indirect bilirubin (P = 0.0006), a higher number of transfused red blood cell units (P = 0.025), and platelet transfusion (P = 0.027).

conclusionDelayed diagnosis appears to be associated with a higher frequency of neurological symptoms and mortality. Intensity of hemolysis and signs of organ ischemia, such as cardiovascular symptoms and focal neurological deficit, are indicators of death risk.
