1 · What the graph read from 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.

2 · The registry

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

There is a well-known inverse association between mortality rate from infectious diseases and improvements in socioeconomic status, even though longer time-series are required to demonstrate this relationship. This general rule seems to apply to mortality from pneumonia in children in the pneumococcal conjugate vaccine (PCV) era. Two recent published secular trend studies spanning from about 30 years among Brazilians under the age of five show either no effect of PCV - not even death rate decline from pneumococcal meningitis - or a modest one (8% reduction). Time-series mortality studies from pneumonia are needed for both, developed and developing countries, those who have implemented PCV or not. Results from these studies would provide critical input and feedback to public health policy makers.
