Fig. 3From: Expression of CFTR, a hallmark gene of ionocytes, is downregulated in salivary glands of Sjögren’s syndrome patientsThe correlation of CFTR expression in SjS patients with and without dry mouth. Comparing the average CFTR expression across SjS patients with non-dry mouth (n = 9) and dry mouth (n = 25) groups reveals that CFTR is lower in SjS patients with a system of dry mouth. Error bars represent SEM. p values are based on Mann–Whitney U testBack to article page
