Impact of prior dengue infection on severity and outcomes: meta-analysis of placebo-controlled trials.
Article in Revista panamericana de salud publica = Pan American journal of public health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Objective: This study evaluated the association between serologically confirmed prior dengue infection and the subsequent risk of virologically confirmed dengue, severe dengue, dengue hospitalization, dengue-related death and all-cause mortality. Methods: A systematic review and meta-analysis were conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed, CINAHL, MEDLINE, the Cochrane Library and Web of Science were searched for reports of phase III randomized controlled trials of vaccine efficacy that had data about the placebo group and information about prior infections and were published between January 1994 and March 2024. Random-effects models were used to calculate combined odds ratios (ORs), and heterogeneity was assessed. Results: Four studies from three phase III trials were included. Participants with prior infection had a lower likelihood of developing virologically confirmed dengue during follow up (OR: 0.85, 95% confidence interval [CI]: 0.75 to 0.98, Conclusions: Prior dengue infection significantly reduced the risk of virologically confirmed dengue and increased the risk of severe dengue, but had no significant effect on dengue hospitalization, dengue-related death or all-cause mortality during follow up. These findings suggest the need to reconsider prior infection as an independent risk factor.
