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

Donor registries and transplantation societies recommend cryopreservation of unrelated donor hemopoietic progenitor cell (HPC) products before the recipient commences conditioning therapy to mitigate the donor and travel risks associated with the COVID-19 pandemic. However, little is known regarding the postthaw quality of such allogeneic products or the effect of precryopreservation storage and processing on these characteristics. We investigated the postthaw CD34+ cell recovery and viability of 305 allogeneic HPC products cryopreserved at 9 laboratories across Australia. Median postthaw CD34+ cell recovery was 76% and ranged from 6% to 122%. Longer transit time before cryopreservation, white cell count (WCC) during storage, and complex product manipulation before cryopreservation were independently associated with inferior postthaw CD34+ cell recovery. Longer precryopreservation transit time and WCC were also associated with inferior postthaw CD34+ cell viability. We conclude that although postthaw CD34+ cell recovery and viability of cryopreserved allogeneic HPC is generally acceptable, there is a significant risk of poor postthaw product quality, associated with prolonged storage time, higher WCC, and complex product manipulation precryopreservation. Awareness of expected postthaw recovery and practices that influence it will assist collection, processing, and transplant centers in optimizing outcomes for transplant recipients.
