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

introductionRespiratory syncytial virus (RSV) causes significant disease in older and comorbid adults. Current UK vaccination recommendations restrict eligibility to adults ≥ 75 years, 65-74 years with chronic respiratory disease or immunosuppression, and those in care homes, but evidence on clinical burden in adults < 75 years with comorbidities is limited. This study assessed patient characteristics, healthcare resource utilization (HCRU), and mortality in adults hospitalized with RSV in England.

methodsPopulation-based retrospective cohort study using linked Clinical Practice Research Datalink Aurum and Hospital Episode Statistics. Adults ≥ 60 years hospitalized with RSV between October 2014 and March 2019 were included. We defined RSV episodes as 90 days post-diagnosis. We defined cases using diagnosis codes for confirmed RSV (RSV-specific) or acute lower respiratory tract infection with exclusion of other causative pathogens (RSV-possible). All-cause HCRU (hospitalizations, critical care admissions, outpatient attendance, primary care consultations, and prescriptions) and case fatality rates were assessed. Results were stratified by age (60-74 and ≥ 75 years), case definitions (RSV-specific, RSV-possible), and comorbidity profiles (chronic respiratory disease, immunocompromised, cardiovascular disease).

resultsA total of 97,712 hospitalized episodes in those aged ≥ 60 years were included in the analysis, of which 785 (0.8%) were RSV-specific cases (n = 338 aged 60-74 years, n = 447 aged ≥ 75 years). In RSV-specific cases, median (IQR) cumulative length of stay (LoS) for those ≥ 75 years was 10.00 (6.00-22.00) days, which was equivalent to or lower than each comorbidity subgroup in those aged 60-74 years, with the longest LoS in those immunocompromised (11.50 [7.00-26.00] days). Critical care admissions were more often observed across comorbidity stratifications (13.85-22.34%) compared to those ≥ 75 years (5.03%). All-cause and RSV-related case fatality rates for RSV-specific cases were highest among those ≥ 75 years (all-cause: 19.3%; RSV-related: 10.3%).

conclusionsHCRU within RSV episodes in those aged 60-74 years across comorbidity profiles was equal to or greater than that in those aged ≥ 75 years. These findings highlight the need to prioritize consideration of comorbidity groups that could benefit from RSV vaccination.
