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
The association between the fluctuation in blood pressure (BP) and the early outcomes of patients with subarachnoid hemorrhage (SAH) remains unclear. Our study aimed to evaluate the value of blood pressure variability (BPV) for predicting the short-term outcomes of patients with acute spontaneous SAH. We collected data from 303 patients hospitalized for acute spontaneous SAH. BP values were recorded at admission and subsequently every 2 h during the initial 24 h of hospitalization. BPV was determined as the standard deviation (SD), the difference between the maximum and the minimum (ΔBP), the coefficient of variation (CV), and successive variation (SV). The outcome at discharge was assessed according to the Glasgow Outcome Scale (GOS). The association between BPV and the outcome was identified by multivariable analysis. The findings showed that the parameters of systolic BPV were independently associated with the outcome in a graded fashion. The odds ratios (OR) for the highest tertiles were as follows: SD 13.9 (95% confidence interval [CI], 4.8-40.4), ΔBP 4.4 (95% CI, 1.6-11.9), CV 16.4 (95% CI, 5.6-48.8), SV 15.8 (95% CI, 5.3-46.9). However, there was no association between a poor outcome and diastolic BPV (all p > 0.05). In conclusion, systolic BPV within the first 24 h after admission was independently associated with the outcomes in SAH patients; the greater the variability was, the worse the outcome.
