Serum BAFF in Indian patients with IIM: a retrospective study reveals novel clinico-phenotypic associations in children and adults.
Article in Clinical rheumatology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
We studied the serum levels of B cell survival factors BAFF and APRIL in patients with idiopathic inflammatory myositis (IIM) and their relation with clinical and autoantibodies. Seventy-five patients (51 females and 24 males) with IIM (Bohan and Peter's criteria 1975) and 25 healthy adults were analyzed for BAFF, APRIL and IL-17 by ELISA, and myositis-specific and associated antibodies (MSA and MAA) using line immunoblot assay. Of the 75 patients, 59 were adults, 42 had Dermatomyositis (DM), and 17 had Polymyositis. Median disease duration was 5 (3-12) months. BAFF levels were higher in IIM than healthy controls [p = 0.001], and in children with jDM than adults [p = 0.026]. BAFF levels were higher in adults with arthritis [p = 0.018], weight loss [p = 0.007], and PAH [p = 0.004]. Among the various MSAs, lowest levels were seen in those with anti-SRP [p = 0.043]. Median follow-up duration was 145 patient years. Twelve patients relapsed, while nine were in drug-free remission. BAFF were similar between these groups. Serum APRIL levels were elevated in limited number of patients with myositis, and the levels did not differ amongst the clinico-serologic phenotypes. IL-17 levels were higher in individuals positive for anti-SRP [p = 0.028]. Serum BAFF levels are elevated in IIM, more so in children. BAFF levels may be useful as biomarker for PAH and arthritis. Anti-SRP positivity is associated with elevated IL-17 levels suggesting role in pathogenesis.
