Prediction efficiency of serum cystatin C for clinical outcome in patients with cardiac resynchronization therapy.
Article in Irish journal of medical science, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis 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
backgroundSince only 60-70% of select patients with chronic heart failure (CHF) are responders in cardiac resynchronization therapy (CRT), this study aimed to investigate whether serum cystatin C (Cys C) can be used to evaluate the effectiveness of CRT in patients with CHF.
methodsSeventy-six patients implanted with CRT were retrospectively enrolled. The concentration of serum Cys C was detected and echocardiography was performed before and after 15 days, 1 month, and 6 months of CRT.
resultsThere were 52 patients (68.4%) who responded to CRT during the follow-up. In the responding group, compared with the pre-CRT, the cardiac function, QRS interval, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), and left ventricular ejection fraction (LVEF) were significantly improved at 6 months after implantation (P < 0.05), but the level of serum Cys C decreased significantly from 1 month after CRT. There was no change of all the parameters in the non-responding group during the follow-up. In the responding group, the ΔCys C% is significantly related to the ΔLVEDV%, ΔLVESV%, and ΔLVEF%. Multivariate linear analysis shows that the ΔCys C% is significantly related to the ΔLVEDV%. The level of serum Cys C before CRT implantation could predict the response to CRT (AUC = 0.78, P < 0.05). Univariate analysis and multivariate analysis demonstrated that the level of Cys C remained independent predictor for CRT (P = 0.028, 95% CI 0.919-1.348).
conclusionsThe level of serum Cys C before CRT implantation is valuable in predicting the response to CRT.
