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

Although hematopoietic growth factors are found at high levels in aplastic anemia (AA) patients, little is known about their dynamic change over time after treatment. We examined plasma concentrations of hematopoietic growth factors sequentially in 55 severe AA patients, including 45 treatment-naive patients who had received immunosuppressive therapy (IST) or IST and eltrombopag, and 10 IST-refractory patients who had received eltrombopag only, focusing on thrombopoietin (TPO). TPO concentrations were much higher than normal in patients before treatment and then decreased in responders but not in nonresponders. We followed up on a cohort of nine patients who obtained stable complete remission for up to 7 years after IST and found that TPO levels declined gradually by 3 months after treatment, accompanying an increase in platelet counts, but stabilized at levels higher than normal. An inverse correlation was noted between TPO levels and platelet counts. The increased plasma TPO levels could be required to maintain normal platelet counts in remission and could also be attributed to reduced consumption by circulating platelets.
