Effect of cryopreservation on lymph node fragment regeneration after autologous transplantation in the minipig model.
Article in Innovative surgical sciences, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionLymphoedema is a worldwide pandemic causing swelling of tissues due to dysfunctional transport of lymph fluid. Present management concepts are based in conservative palliation of symptoms through manual lymphatic drainage, use of compression garments, manual lymph drainage, exercise, and skin care. Nevertheless, some curative options as autologous lymph node transplantation were shown to reduce lymphoedema in selected cases. Lately, some concern has arisen due to reports of donor site morbidity. A possible solution could be the development of artificial lymph node scaffolds as niches of lymphatic regeneration. Engineering these scaffolds has included cryopreservation of lymph node stroma. However, the effects of cryopreservation on the regeneration capacities of these organs were unknown. MATERIALS AND
methodsHere, we used the minipig animal model to assess lymphatic regeneration processes after cryopreservation of autologous lymph nodes. Superficial inguinal lymph nodes were excised and conserved at -80°C for 1 month. Thereafter, lymph node fragments were transplanted in the subcutaneous tissue.
resultsRegeneration of the lymph nodes was assessed five months after transplantation. We show that lymph node fragment regeneration takes place in spite of former cryopreservation. Transplanted fragments presented typical histological appearance. Their draining capacity was documented by macroscopic transport of Berlin Blue dye as well as through SPECT-CT hybrid imaging. DISCUSSION: In conclusion, our results suggest that processes of cryopreservation can be used in the creation of artificial lymph node scaffolds without major impairment of lymph node fragments regeneration.
