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

backgroundDevices that record from the finger have potential practical advantages for home monitoring of blood pressure. However, digital arterial pressure may vary substantially from that in the brachial artery, due to the influence of peripheral wave reflection.

aims(1) To compare digital arterial pressure, as measured with the Omron F3 device, with brachial arterial pressure and (2) to determine the effect on digital pressure of changing local vascular resistance.

methodThe subjects were normotensive young adult non-smokers (12 males, 14 females). Pressures were recorded simultaneously from arm (using an Omron HEM-705CP) and finger with subjects seated and both recording sites at the level of the xiphisternum. Measurements were made at ambient temperatures of 19 degrees C and 30 degrees C; at rest, during brief contralateral hand cooling and after hand rewarming.

resultsIn many cases, resting finger values differed substantially from arm values; sometimes by 20 mm Hg or more. The extent of individual variations was not correlated with gender or temperature. However, group pressure differences between the sites were greater in females at ovulation than at menstruation and greater at 30 degrees C than at 19 degrees C. For all groups, pressure differences between sites were attenuated during hand cooling and restored by rewarming.

conclusionsFinger blood pressure, as measured with the Omron F3, misestimates brachial blood pressure in a high proportion of normal subjects. This error is increased under circumstances associated with cutaneous vasodilation. The Omron F3 does not appear to be suitable for unsupervised home monitoring of blood pressure.
