High intradialysis diastolic blood pressure variability is an independent predictor of all-cause mortality.

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
backgroundTo investigate the relationship between intradialytic blood pressure variability (BPV) and all-cause mortality in patients on maintenance hemodialysis (MHD).
methodsIntradialysis blood pressures and other clinical characteristics of 142 MHD patients who were on dialysis from 08/2016 to 07/2017 were retrospectively collected. Death events were followed and recorded in the following at least 36 months. The systolic/diastolic blood pressure coefficient of variation (SBPCV/DBPCV) and the systolic/diastolic average real variation of blood pressure (SBPARV/DBPARV) were calculated. Univariate and multivariate Cox proportional hazards models were used to examine the relationship between intradialytic BPV and all-cause mortality.
resultsAmong the 142 MHD patients (age 61.5 ± 15.0 years, males 63.6%). High BPV, including the SBPCV and DBPCV at the beginning of dialysis, intradialytic SBPCV and DBPCV, intradialytic DBPARV, and the DBPCV at the end of dialysis, were significantly associated with all-cause death (
conclusionsHigh intradialytic DBPARV was an independent risk factor for all-cause mortality. Intradialysis BPV is mainly impacted by ultrafiltration volume.
