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

Neoehrlichiosis is caused by infection with the tickborne intracellular bacterium Neoehrlichia mikurensis. We describe 3 cases of direct antiglobulin test-negative hemolytic anemia in rituximab-treated patients infected with tickborne N. mikurensis bacteria in Norway during 2024-2025. All 3 patients had splenomegaly and night sweats. The hemolysis ranged from mild with compensated hemolysis to severe transfusion-dependent hemolysis that resulted in splenectomy in 1 case. All patients experienced complete resolution of hemolytic anemia and other symptoms of infection after eradication therapy with doxycycline for 21 days. Neoehrlichiosis should be considered as a curable cause of hemolytic anemia in N. mikurensis-endemic regions.
