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
introductionA narrow fragmented QRS complex (fQRS) indicates myocardial fibrosis and hypertensive cardiomyopathy in hypertensive patients. However, no study has investigated the importance of localization of fQRS on electrocardiography (ECG) in these subjects.
aimTo investigate the association between circadian blood pressure (BP) pattern and localization of fQRS on ECG.
methodsA total of 291 hypertensive patients who had fQRS in anterior or inferior leads were included into the study. Patients were divided into two groups according to localization of fQRS in inferior or anterior leads. All patients underwent a 24-h ambulatory blood pressure monitoring for detailed evaluation of circadian BP pattern. The association between localization of fQRS and non-dipping was investigated.
resultsAmong study population, 182 (62.5%) patients had fQRS in inferior leads and 109 (37.5%) patients had fQRS in anterior leads. The frequency of patients with non-dipping BP pattern was significantly higher in patients with fQRS in anterior leads compared to patients with fQRS in inferior leads (47.7% vs 24.1%, p < 0.001). Moreover, the frequency of fQRS in anterior leads was significantly higher in non-dippers compared to dippers (64.6% vs. 24.1%, p < 0.001). Furthermore, in multivariate analysis, presence of fQRS in anterior leads was found to be an independent predictor of non-dipping BP pattern in hypertensive patients (OR: 1.748, 95% CI 1.362-2.446, p < 0.001).
conclusionsPresence of fQRS in anterior leads is significantly associated with non-dipping BP pattern in hypertensive patients. Therefore, localization of fQRS on ECG may provide useful information regarding further risk assessment of hypertensive subjects.
