Cost-effectiveness analysis of pneumococcal polysaccharide vaccination from age 60 in São Paulo State, Brazil.
Article in Human vaccines, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 3 of them syntheses that pooled it.
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
Vaccination of adults aged 60 years and older against Streptococcus pneumonia is not recommended in Brazil. The 23-valent polysaccharide pneumococcal vaccine (PPV23) is only available for institutionalized persons or with underlying diseases despite the substantial medical and economic burden related to pneumococcal infections in adults over than 59 years. The study aimed at evaluating the cost effectiveness of implementing a large PPV program in this population. This analysis was performed using a static decision tree model. Demographic and epidemiological data were obtained from Brazilian official sources and international literature. Economic data were obtained from a study performed in 2007 in a public and a private hospital located in Sao Paulo. Vaccination was assumed to protect for 5 years with 60% effectiveness against bacteremic pneumococcal pneumonia (BPP) and 21% effectiveness against non bacteremic pneumococcal pneumonia (NBPP). Deterministic and sensitivity analyses were performed. The pneumococcal polysaccharide vaccination saved 5,218 life year gained (LYG). The vaccination program was found to be cost effective in the social security and public health care perspectives with a mean incremental cost-effectiveness ratio of R$10,887 and R$8,281 per LYG respectively. Results were sensitive to the vaccine effectiveness against NBPP, the incidence and case-fatality rate of NBPP. From a societal perspective, PPV23 program for adults 60 and older was found to be cost-saving. Pneumococcal polysaccharide vaccination is clinically and economically favored over the present vaccination strategy, in which persons aged over 59 years in Sao Paulo, have not been vaccinated.
