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

The patterns of tryptase normalization, KITD816V clearance and establishment of donor cell chimerism were analysed in 13 patients with systemic mastocytosis and associated haematological neoplasm (AHN) after haematopoietic cell transplantation (HCT). The molecular marker of systemic mastocytosis (SM) (KITD816V) simultaneously disappeared (median + 36 days) with the establishment of donor chimerism (median: +31 days post-HCT; Pearson correlation: -0.99, p < 0.001). In contrast, tryptase normalized median of +228 days after HCT with significant delay to KITD816V clearance (p = 0.01) and full donor chimerism (p = 0.04). Faster normalization was observed after radiation-based conditioning and removal of an infiltrated spleen, while persistence was not associated with relapse of AHN.
