Response to Shami et al. 'Evaluating the cost-effectiveness of a sequential pneumococcal vaccination compared to single dose vaccination strategy for adults in Hong Kong' (Hum Vacc Immunother 2020).
Article in Human vaccines & immunotherapeutics, 2021. 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
The recently published article by Shami et al. describes a cost-effectiveness analysis of sequential pneumococcal vaccination with 13-valent pneumococcal conjugate vaccine (PCV13) followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23), compared with a single PPSV23 dose, in adults in Hong Kong. Sequential vaccination was cost-saving versus PPSV23 alone. The model assumed vaccine effectiveness (VE) of 0% for PPSV23 against all-cause non-bacteremic pneumonia; this was based on studies with flawed methodologies and studies that did not evaluate non-bacteremic pneumococcal disease. In recent studies and meta-analyses, PPSV23 VE pneumococcal pneumonia, including against non-bacteremic pneumococcal pneumonia, ranged from 27% to 64%. In other cost-effectiveness analyses, assumptions for PPSV23 VE against non-bacteremic pneumococcal pneumonia, had dramatic effects on cost-effectiveness estimates. Future analyses must carefully consider PPSV23 VE assumptions to ensure accuracy.
