Temporal variation in total transforming growth factor β2 (TGFβ2) levels, expressed as mean (SD), in the CSF of patients with (filled bars) and without (open bars) chronic hydrocephalus. p Values above error bars are statistically significant differences in cytokine levels between those haemorrhagic patients that went on to develop chronic communicating hydrocephalus compared with those that did not. *p<0.05, **p<0.01, those haemorrhagic patient groups that are significantly different from the control patient group with non-haemorrhagic chronic hydrocephalus. dph, days post-haemorrhage; n, number of patients.
