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

Antimicrobial-resistant bacteria (ARBs) are serious global threat because they make it difficult to treat infections with antibiotics. Recently, it has been demonstrated that ARBs are isolated from the oral cavities of elderly individuals in long-term care facilities. Because oral ARBs can cause systemic diseases such as bacteraemia and aspiration pneumonia, more attention must be given to protect the overall health of elderly people. To understand the prevalence of oral ARBs, more studies are needed in addition to previous studies. In this study, we investigated oral ARBs in elderly people receiving home health care (HHC) who had different lifestyles as residents in long-term care facilities. Among 98 HHC participants, Staphylococcus aureus, including 8 methicillin-resistant S. aureus (MRSA) strains, was isolated from 31 participants (31.7%), and 3rd-generation cephalosporin-resistant gram-negative bacteria (GNARB) were isolated from 18 participants (17.8%). An analysis of the relationship between oral ARBs and clinical status revealed that S. aureus/MRSA isolation was correlated with denture condition, while GNARB isolation was correlated with tube feeding. This study is the first comprehensive analysis of ARB carriage in the oral cavities of elderly people in HHCs. These results demonstrate the potential risk of oral ARB carriage and the importance of infection control in HHCs.
