Meta-analysis of the risk of autoimmune thyroiditis, Guillain-Barré syndrome, and inflammatory bowel disease following vaccination with AS04-adjuvanted human papillomavirus 16/18 vaccine.

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
purposeTo assess the risk of three autoimmune diseases - autoimmune thyroiditis (AIT), Guillain-Barré syndrome (GBS), and inflammatory bowel disease (IBD) - in females following AS04-HPV-16/18 vaccination.
methodsThis meta-analysis included data from 18 randomized controlled trials, one cluster-randomized trial, two large observational retrospective cohort studies, and one case-control study. Following vaccination, a risk window of 2 years was defined for AIT and IBD and 42 days for GBS. Odds ratios (ORs) were estimated using three methods: meta-analysis inverse-variance with continuity correction (primary analysis), pooled estimate, and beta-binomial regression.
resultsIn all studies apart from the case-control study, 154 398 exposed and 1 504 322 non-exposed subjects were included, among whom there were 141 and 1972 cases of (autoimmune) thyroiditis; 2 and 2 cases of GBS; and 43 and 401 cases of IBD, respectively. In the case-control study, there were 97 cases of AIT and 13 of GBS; matched with 802 and 130 controls, respectively. The primary analysis OR estimates were 1.46 (95% confidence interval [CI] 1.22-1.76), 11.14 (2.00-61.92), and 1.11 (0.75-1.66) for (autoimmune) thyroiditis, GBS, and IBD, respectively.
conclusionsThis meta-analysis did not show an increased risk of IBD following vaccination with AS04-HPV-16/18. The 1.5-fold increased risk of (autoimmune) thyroiditis does not allow us to conclude about a causal association. For GBS, the very low number of cases and wide 95% CIs negate any firm conclusion.
