Short-term reproducibility of ambulatory blood pressure measurements: a systematic review and meta-analysis of 35 observational studies.

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
objectiveA systematic review on the reproducibility of ambulatory blood pressure measurements (ABPM) has not yet been conducted. This meta-analysis compared 24-h/daytime/night-time SBP and DBP mean values and SBP/DBP nocturnal dipping status from ABPMs in participants with or without hypertension.
methodsOvid MEDLINE, EMBASE, and CINAHL Complete databases were searched for articles published before 3 May 2019. Eligible studies reporting a 24-h ABPM repeated at least once within 1 month were included. The mean daytime/night-time/24-h BP values, percentage of nocturnal dipping, and proportion of nondippers were compared between the first and second day of measurements, and the proportion of participants with inconsistent dipping status were estimated using a random effect model.
resultsPopulation-based analysis found a 0-1.1 mmHg difference between the first and second ABPM for 24-h/daytime/night-time SBP and DBP and 0-0.5% for percentage of SBP/DBP nocturnal dipping. The proportion of non-dippers was not different between the first and second ABPM. Intra-individual analysis found that the 95% limit of agreements (LOA) for SBP/DBP were wide and the 95% LOA for daytime SBP, common reference to diagnose hypertension, ranged -16.7 to 18.4 mmHg. Similarly, 32% of participants had inconsistent nocturnal dipping status.
conclusionABPM had excellent reproducibility at the population level, favouring its application for research purposes; but reproducibility of intra-individual BP values and dipping status from a 24-h ABPM was limited. The available evidence was limited by the lack of high-quality studies and lack of studies in non-Western populations.
