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
backgroundBlood pressure (BP) naturally undergoes fluctuations and variations, particularly during anesthesia administration during surgery, hemodialysis, upper and lower gastrointestinal endoscopy, exercise testing, arterial and venous catheterization, and rehabilitation. These changes in BP may lead to life-threatening events.
objectivesThe performance of the Omron HBP-M4500 device in monitoring blood pressure (BP) in the upper arm was validated according to the International Organization for Standardization (ISO) 81060-2:2018+amendment (Amd) 1:2020 protocol.
methodsThe device was used to assess 113 participants in the inflation mode, and 107 participants in the deflation mode. All the patients fulfilled the inclusion criteria, including the arm circumference range and systolic and diastolic BP levels, outlined in the protocol. Data validation and analysis were performed according to the manufacturer's instructions.
resultsIn criterion 1, the mean ± standard deviation (SD) values of the differences between the test device and reference BP were -0.6 ± 5.80/2.8 ± 6.78 mmHg (systolic/diastolic) and -1.0 ± 5.35/3.2 ± 6.52 mmHg for the inflation and deflation modes, respectively. These data fulfilled the ISO81060-2:2018+Amd1:2020 requirements of ⩽ 5 ±⩽ 8 mmHg. In criterion 2, the differences were -0.6 ± 4.44/2.8 ± 6.26 and -1.0 ± 3.84/3.2 ± 6.09 mmHg for the inflation and deflation modes, respectively, fulfilling criterion 2 with SD values of ⩽ 6.91 and ⩽ 6.87 for systolic BP and ⩽ 6.34 and ⩽ 6.14 for diastolic BP in the inflation and deflation modes, respectively. These two criteria were fulfilled in both studies.
conclusionThe Omron HBP-M4500 device, either in inflation or deflation mode, fulfilled the criteria outlined in the ISO protocol. Therefore, this device is valuable for BP measurement in clinical and hospital settings.
