Utilization of arterial pulse waveform analysis during non-cardiac surgery in Japan: a retrospective observational study using a nationwide claims database.
Observational study in Journal of anesthesia, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Arterial pulse waveform analysis (APWA) is used for cardiac output monitoring. However, data on the frequency of and patient characteristics for specialized pressure transducer for APWA (S-APWA) use are lacking. We retrospectively identified 175,201 patients aged 18 years or older, who underwent non-cardiac surgery under general anesthesia with an arterial catheter from January 1, 2014, to December 31, 2016. We extracted data on patient demographics, comorbidities, surgical and anesthesia characteristics, and hospital characteristics. Among the full study cohort, 24,605 (14.0%) patients were monitored using S-APWA. Further, the use of S-APWA was higher in patients undergoing high-risk surgery than in those undergoing low-risk surgery [high vs low: adjusted odds ratio (aOR) 1.95; 95% confidence interval (CI) 1.76-2.15, moderate vs low: aOR 1.11; 95% CI 1.01-1.22] and those with more comorbidities than in those with less comorbidities (high vs low: aOR 1.49; 95% CI 1.42-1.56, moderate vs low: aOR 1.25; 95% CI 1.20-1.31). S-APWA use was significantly associated with both surgery risk and patients' comorbidities. In conclusion, our study may provide a benchmark for future studies related to the appropriate use of S-APWA.
