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

backgroundThe purpose of this study was to investigate whether circulating pyruvate kinase M2 (PK-M2) levels are elevated in the peripheral blood and to assess their association with diagnosis and prognosis in patients with heart failure (HF). METHODS AND

resultsWe conducted a prospective investigation involving 222 patients with HF and 103 control subjects, measuring PK-M2 concentrations using ELISA. The primary outcome, assessed over a median follow-up of 2 years (interquartile range: 776 to 926 days), was the time to the first occurrence of either rehospitalization for worsening HF or cardiovascular death. Patients with HF had higher PK-M2 levels than controls (17.4±4.1 versus 7.8±2.3 U/mL,

conclusionsElevated PK-M2 levels are associated with primary outcomes and rehospitalization for worsening heart failure in patients with HF. These findings suggest that PK-M2 is a potential biomarker for HF diagnosis and prognosis, warranting consideration for serial patient assessment.
