Polyclonal B-cell expansion in the cerebrospinal fluid of patients with pseudotumor cerebri.
Article in Journal of clinical immunology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
To investigate the hypothesis that pseudotumor cerebri (PTC) is associated with humoral immunity, we analyzed immunoglobulin heavy chain variable region (Ig-VH) genes of B cells in the cerebrospinal fluid (CSF) of 10 patients with PTC. Using RT-PCR and sequencing techniques, intrathecal B-cell Ig-VH genes were amplified in 6 of 10 PTC samples. Sequence analysis of complementarity-determining region 3 (CDR 3) and VH genes revealed a polyclonal intrathecal B-cell expansion in these patients. The nucleotide sequences showed that one-third of analyzed sequences had a high replacement to silent nucleotide substitution ratio, indicating an antigen-driven T-cell-dependent intrathecal B-cell proliferation. Moreover, other one-third had germline VH genes without or with a few nucleotide mutations, suggesting a T-cell-independent natural B-cell-mediated humoral immunity in the CNS of these patients. Our results suggest that both T-cell-dependent and T-cell-independent humoral immunity are present in the CSF of PTC.
