1 · What the graph read from 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.

2 · The registry

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 evaluate ANA specificity using the fully automated multiplexed fluorescent microsphere immunoassay in patients affected either by rheumatoid arthritis or ankylosing spondylitis who developed strong positivity for ANA as assessed by indirect immunofluorescent method on HEp-2 cells during infliximab treatment. Three men affected by ankylosing spondylitis and 12 women affected by rheumatoid arthritis who developed ANA positivity at high titres during infliximab treatment underwent the identification of ANA specificity by multiplexed fluorescent microsphere immunoassay; moreover anti-DNA and anti-ENA antibodies were tested by indirect immunofluorescence and ELISA method, respectively. In 4 out of 15 cases, the determination of ANA reactivity by multiplexed fluorescent microsphere immunoassay was also performed on the serum collected before infliximab administration. One patient affected by rheumatoid arthritis showed multiple ANA reactivities against SS-A, SS-B, RNP, Sm, Jo-1 and histones; one patient affected by ankylosing spondylitis resulted positive for the same autoantibodies, except for anti-Sm antibody. Moreover, two patients, one with rheumatoid arthritis and one with ankylosing spondylitis, showed single antibody specificity to SS-B and RNP, respectively. The remaining 11 cases did not show any positivity. Instead, all the patients resulted negative for anti-ENA antibodies by the ELISA method. In the four cases tested for ANA specificity by multiplexed fluorescent microsphere immunoassay before and after infliximab administration no difference was found. The search for anti-DNA antibody always resulted negative by both the traditional immunofluorescent assay and the novel technique. The use of multiplexed fluorescent microsphere immunoassay in patients treated with infliximab with ANA positivity at high titres allowed to find some ANA specificities which were not revealed by ELISA method. Nevertheless, the majority of patients resulted negative in spite of ANA positivity at high titres; the molecular target of ANA which develop after infliximab administration still remains to be identified.
