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

Autoimmune hemolytic anemia (AIHA) is rare in solid tumors and may represent a paraneoplastic phenomenon. We describe the case of a 73-year-old woman with unresectable pancreatic adenocarcinoma who developed steroid-refractory warm AIHA. Prednisolone partially improved her anemia but not her hemolysis. Chemotherapy with modified FOLFIRINOX followed by gemcitabine plus nab-paclitaxel improved both the tumor and anemia, enabling steroid tapering. Conversion surgery revealed the ectopic expression of band 3 in tumor cells. This case suggests that anti-band 3 antibodies may mediate paraneoplastic AIHA and emphasizes the importance of tumor control in steroid-refractory cases.
