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.
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
BACKGROUND/
aimThe COVID-19 pandemic has had a significant impact on the current management of allotransplanted patients in whom fresh hematopoietic stem cells (HSCs) were replaced by cryopreserved ones. The aim of the study was to determine the efficacy and safety of cryopreserved HSCs when compared with the fresh ones. PATIENTS AND
methodsA retrospective analysis of 254 allogeneic stem cell transplantations (HSCT) procedures performed between 2020-2021 included the following donors: matched related (MRD; n=68), matched unrelated (MUD; n=148) and haploidentical (HID; n=38). 50% of patients (non-cryo group) received fresh grafts, whereas the remaining patients (cryo group) were transplanted with cryopreserved cells.
resultsNo differences in terms of median days to neutrophil [MRD/MUD/HID cryo- and non-cryo groups: 17 vs. 16 (p=0.27), 19 vs. 18 (p=0.83), 22 vs. 22 (p=0.83) days, respectively] and platelet [MRD/MUD/HID cryo- and non-cryo groups: 14 vs. 14 (p=0.25), 17 vs. 17 (p=0.33), 21 vs. 19 (p=0.36) days, respectively] engraftments were demonstrated. Among MUD graft recipients, platelet engraftment rates were 81% in the cryo- and 96% in the non-cryo group (p=0.01). OS rates were comparable at 1 year after HSCT between MRD/MUD/HID cryo- and non-cryo groups: 53% vs. 60% (p=0.54), 60% vs. 66% (p=0.5), 50% vs. 41% (p=0.56), respectively.
conclusionDuring the COVID-19 pandemic, cryopreserved HSCs did not have a negative impact on median engraftment time and OS when compared to fresh HSCs. In the MUD group, platelet engraftment rate was lower in cryopreserved HSC recipients.
