Parental Rheumatoid Arthritis, Child Mortality, and Case Fatality: A Nationwide Cohort Study.
Article in Arthritis care & research, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveWe have previously reported increased long-term morbidity in children of parents with rheumatoid arthritis (RA). Here we assess child mortality and case fatality in the same cohort.
methodsAll singletons born in Denmark from 1977 to 2008 were identified through linkage of Danish national registries. Cox proportional hazards models were used to calculate hazard ratios (HRs) of death from all causes among children exposed to parental RA, compared to unexposed children. Risk of death after infection or respiratory diseases was also assessed for children below the age of 5 years.
resultsThis study followed 1,917,723 newborns for an average of 16 years. Of these, 13,556 were exposed to maternal RA and 6,330 to paternal RA. Overall mortality rates in children exposed to maternal or paternal RA did not differ from those in unexposed children (HR 0.98 [95% confidence interval (95% CI) 0.84-1.15] and 1.08 [95% CI 0.86-1.36], respectively), nor did the risk of death below the ages of 5 years, 3 years, or 1 year. In the group of children below the age of 5 years, 6,106 children of parents with RA were diagnosed with respiratory diseases and 3,320 with infectious diseases. The case fatality rate in children with these diseases was not significantly higher than in unexposed children (HR 1.11 [95% CI 0.74-1.66] and 0.84 [95% CI 0.52-1.35], respectively).
conclusionChildren of parents with RA had similar mortality rates as other children, as well as after diagnoses of respiratory or infectious diseases.
