Differential Utility Losses in Herpes Zoster Cases Between Vaccinated and Unvaccinated Subjects: A Meta-analysis of Three Clinical Trials.

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.

Abstract
BACKGROUND AND
objectiveRecombinant zoster vaccine (RZV) is approved in adults for the prevention of herpes zoster. The effect of RZV in moderating the severity of breakthrough cases of herpes zoster has been noted but not explicitly quantified before. In this study, a meta-analysis was undertaken to estimate differential utility losses between unvaccinated (Placebo) and vaccinated (RZV) subjects in breakthrough cases of herpes zoster from three RZV clinical trials.
methodsDifferential utility losses between the two groups were estimated in units of quality-adjusted life-years (QALYs), leveraging aggregate patient data from the ZOE-50 (NCT01165177), ZOE-70 (NCT01165229), and ZOE-HSCT (NCT01610414) clinical trials. Differential utility losses and the ratio of mean utility losses were analyzed using random-effects and fixed-effects meta-regression models.
resultsThe mean QALY loss differences between the unvaccinated (Placebo) and vaccinated (RZV) groups were 0.008, 0.004, and 0.011 in the ZOE-50, ZOE-70, and ZOE-HSCT studies, respectively, yielding an overall estimated difference of 0.007 (95% confidence interval 0.002-0.012) QALYs. Quality-adjusted life-year loss in the vaccinated group was estimated to be 35.5% of the value in the placebo group. A sensitivity analysis estimated an overall difference of 0.005 (95% confidence interval 0.001-0.009) QALYs, corresponding to 48.6% of the QALY loss value in the placebo group.
conclusionsRecombinant zoster vaccine is effective in alleviating disease severity in breakthrough cases of herpes zoster. The results may be useful in distinguishing QALY losses between vaccinated and unvaccinated cohorts in health economics studies, particularly cost-effectiveness analyses.
