Is primary Sjögren's syndrome a risk factor for malignancies different from lymphomas? What does the literature highlight about it?
Review in Reumatologia. 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
backgroundPrimary Sjögren's syndrome (pSS) is a chronic systemic autoimmune disease with an elevated risk of developing lymphoproliferative malignancies (LM). Whether pSS is a risk factor or not for non-lymphoma malignancies (NLM) has been scarcely evaluated in the literature. Age is per se a risk factor for malignancies: patients over 70 years old have 4 times higher risk for cancers than adults. Even if the mean age of pSS onset usually is in the 4 MATERIAL AND
methodsTo evaluate pSS as a risk factor for NLM we performed a systematic electronic search on PubMed in the period 2006-2016 to identify all the publications on this topic. The studies were eligible for inclusion if they reported specific Standardized Incidence Ratio (SIR) with 95% CI. Studies that did not report sufficient published and/or original data were excluded.
resultsOnly 7 articles of 494 that we found in PubMed fulfilled the inclusion criterion. In the vast majority of these, SIR values were not statistically significant for NLM. The occurrence of NLM after LM was statistically significant in some studies and a NLM represented the most frequent cause of death. The possibility that NLM may represent a paraneoplastic syndrome seems much more frequent than LM, the risk of which increases with time after the diagnosis. Data regarding the neoplastic weight of EOpSS are mainly pointed out by case reports.
conclusionsPrimary Sjögren's syndrome is not associated with an increased risk for NLM. However the possibility that NLM may appear after recovery from lymphoma should be carefully considered because it could be cause of the patient's death. Similarly the possibility that NLM may represent a paraneoplastic syndrome must be highlighted. The relationship between EOpSS and SIRs for NLM should be deepened with studies on ad hoc cohorts.
