1 · What the graph read from 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.

2 · The registry

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

Introduction: less invasive approach (LIS) has recently become increasingly used for left ventricular assist device (LVAD) implantation. However, the impact of surgical access on pump position and clinical outcomes comparing LIS-LVAD implantation to full sternotomy (ST) has not been well discussed. Methods: Between April 2010 and February 2021, a total of 237 consecutive patients received a LVAD, 76 (32.1%) of whom underwent the LIS approach and 161 (67.9%) of whom underwent ST. The clinical outcomes were retrospectively reviewed, and data of 66 comparable patients from each group extracted by propensity score matching were analyzed. For the analysis of pump position, cannula coronal angle (CCA,°) and pump diaphragm depth (PDD, mm) of LVAD were measured according to postoperative chest x-ray. Results: The mean age of all patients was 57.7 ± 11.3 years, 204 cases were male (86.1%), and 48 cases resulted in in-hospital death (20.3%). There was no significant impact on clinical outcomes according to surgical approach in matched groups. There was also no significant difference regarding pump position between two different access groups. A larger PDD was associated with both in-hospital death (60.2 ± 25.8 vs. 43.4 ± 31.3, Conclusions: Our results indicate that LVAD implantation via LIS approach is safe yielding comparable outcomes with ST approach. Regarding spatial positioning of LVAD via LIS approach, larger PDD, may predict worse clinical outcomes.
