Diastolic index as a short-term prognostic factor in heart failure with preserved ejection fraction.
Observational study in Open heart, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled it.
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
objectiveDuring follow-up time, the value of prognostic factors may change, especially in the elderly patients, and the altered extent may affect the prognosis. We aimed to clarify the significance of the ratio of diastolic elastance (Ed) to arterial elastance (Ea), (Ed/Ea=(E/e')/(0.9×systolic blood pressure)), an afterload-integrated diastolic index, in relation to follow-up periods and other laboratory factors, on the prognosis of elderly patients with heart failure with preserved ejection fraction (HFpEF).
methodsWe studied 552 HFpEF patients hospitalised for acute decompensated heart failure (men/women: 255/297). Blood testing and transthoracic echocardiography were performed before discharge. The primary endpoint was all-cause mortality.
resultsDuring a median follow-up of 508 days, 88 patients (men/women: 39/49) had all-cause mortality. During the first year after discharge, Ed/Ea (p=0.045) was an independent prognostic factor in association with albumin (p<0.001) and N-terminal pro-brain natriuretic peptide (NT-proBNP, p=0.005) levels after adjusting for age and sex in the multivariate Cox hazard analysis. However, at 1 to 3 years after discharge, no other significant prognostic factors, except for albumin level (p=0.046), were detected. In the subgroup analysis, albumin, but not NT-proBNP level, showed a significant interaction with Ed/Ea for prognosis (p=0.047).
conclusionThe prognostic significance of a haemodynamic parameter such as Ed/Ea may be valid only during a short-term period, but that of albumin was persisting during the entire follow-up period in the elderly patients. The clinical significance of prognostic factors in HFpEF patients may differ according to the follow-up period.
