Effects of Decompressive Cervical Surgery on Blood Pressure in Cervical Spondylosis Patients With Hypertension: A Time Series Cohort Study.
Article in International journal of spine surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe blood pressure of cervical spondylosis (CS) patients with hypertension often returns to normal after decompressive cervical surgery (DCS). However, the effect of DCS on the blood pressure of patients with CS has not been rigorously studied.
methodsWe recruited 50 consecutive CS patients with hypertension from 2014-2017 and investigated the changes in blood pressure after DCS using a time series design. Ambulatory blood pressure monitoring (ABPM) was performed at 3 and 0 days before DCS and at 30 and 90 days after DCS. The primary outcome was mean 24-hour systolic blood pressure (SBP). Secondary outcomes included mean 24-hour diastolic blood pressure (DBP), office blood pressure, and the percentage of patients on antihypertensive medication. Paired
resultsThe mean 24-hour SBP did not vary significantly among 4 time points (134.5 ± 14.7, 132.8 ± 14.7, 131.5 ± 13.3, and 133.2 ± 14.6, respectively;
conclusionsThis study confirmed previous findings of reduction in office blood pressure associated with DCS among CS patients with hypertension. However, this was not confirmed by multiple-time series of 24-hour ABPM. LEVEL OF EVIDENCE: 3.
