Human cytomegalovirus (HCMV) UL44 and UL57 specific antibody responses in anti-HCMV-positive patients with systemic sclerosis.
Article in Clinical rheumatology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
The role of human cytomegalovirus (HCMV) has been postulated as a trigger of systemic sclerosis (SSc). The aim of the study was to assess the prevalence of antibodies against HCMV UL44 and UL57 antigens not tested in the past. Sixty SSc patients, 40 multiple sclerosis and 17 normal controls (NCs), all anti-HCMV positive, were tested by immunoblotting. Reactivity to HCMV antigens, expressed as arbitrary units (AUs), was assessed for correlation with clinical and immunological parameters, including types of SSc-related autoantibodies. Anti-UL44 and anti-UL57 HCMV antibodies were present in 3/60 (5%) and 58/60 (96.7%) SSc patients, respectively (p < 0.001). Anti-UL57 antibodies were present in 35/40 (87.5%) MS patients and 16/17 (94.1%) NCs (SSc vs MS, MS vs NC, p = ns). Strong (50-75 AU) and very strong (75-100 AU) anti-UL57 immunoreactivity was found in 24 (41.4%) and 22 (37.9%) SSc patients, respectively (p = ns). Dilution experiments showed anti-UL57 antibody persistence in up to 1/5000. Overall, there was no difference in the frequency or the magnitude of anti-UL57 immunoreactivity between diffuse cutaneous systemic sclerosis and limited cutaneous systemic sclerosis patients (96.67 vs 96.67%; 65.45 ± 20.19 vs 64.31 ± 21.11 AU, p > 0.05) but strong anti-UL57 reactivity were more frequent in SSc compared to NCs (p = 0.007). Anti-UL57 reactivity was not inhibited by SSc-specific autoantigens. Anti-UL57 seropositivity did not correlate with demographic, clinical or immunological features of SSc. Anti-HCMV UL57 antibodies are universally present in anti-HCMV-positive patients with SSc, while those against UL44 are rarely seen. Because anti-UL57 lack disease specificity and are not involved in cross-reactive responses, their immunopathogenetic potential is to be questioned.
