Size of the population of CD4+ natural killer T cells in the liver is maintained without supply by the thymus during adult life.
Article in Immunology, 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Given that there are few natural killer T (NKT) cells in the liver of athymic nude mice and in neonatally thymectomized mice, it is still controversial whether all NKT cells existing in the liver are supplied by the thymus or if some such cells develop in the liver. To determine whether or not NKT cells are consistently supplied from the thymus during adult life, thymectomy was conducted in mice at the age of 8 weeks. Interestingly, the proportion and number of CD4+ NKT cells increased or remained unchanged in the liver after adult thymectomy and this phenomenon continued for up to 6 months after thymectomy. The administration of alpha-galactosylceramide induced severe cytopenia (due to apoptosis) of CD4+ NKT cells in the liver on day 1, but subsequent expansion of these NKT cells occurred in thymectomized mice similar to the case in normal mice. However, in thymectomized mice given lethal irradiation (9.5 Gy) and subsequent bone marrow transfer, the population of CD4+ NKT cells no longer expanded in the liver, although that of CD8+ NKT cells did. These results suggest that thymic CD4+ NKT cells, or their progenitors, may migrate to the liver at a neonatal stage but are not supplied from the thymus in the adult stage under usual conditions. CD8+ NKT cells can be generated in the liver.
