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

backgroundMinimally invasive surgery (MIS) use for ventral hernia repair has increased over the last decade. Whether outcomes are improved by robotic assistance remains a subject of debate. The aim of this study is to evaluate outcomes (including cost, complications, length of stay (LOS), and pain medication utilization) in patients who underwent an open (OVHR), laparoscopic (LVHR), or robotic (RVHR) ventral hernia repair (VHR).

methodsThe Vizient database was queried using ICD-9 procedure and diagnosis codes for patients who underwent VHR from January 2013 to September 2015. Complications, 30-day readmission, mortality, LOS, cost, and intra-hospital opiate utilization were analyzed using IBM SPSS v.23.0.0.0. Median tests with post hoc pairwise comparisons, Fischer's exact, and Pearson's chi-squared test with Bonferroni correction were applied where appropriate, with α = 0.05.

results46,799 patients (OVHR: N = 39,505, LVHR: N = 6829, RVHR: N = 465) met the criteria and patients in each group had similar demographics (Table 1). OVHR was associated with significant increased overall complications, 30-day readmission, LOS, and postoperative pain use compared to RVHR or LVHR. OVHR had higher mortality and postoperative infection rates than LVHR. RVHR had significantly higher rates of complications and postoperative infections compared to LVHR, although there was no difference in mortality, 30-day readmission, LOS, and postoperative pain medication use. Mean direct cost of surgery was significantly higher for RVHR, followed by OVHR and LVHR.

conclusionsOverall patient outcomes were improved in the LVHR and RVHR groups compared to the open approach. However, RVHR patients did not have significant improvement compared with the LVHR group in either short-term outcomes or opiate medication used. While RVHR surgery was the most expensive modality, OVHR was also significantly costlier than LVHR, which was the least expensive. Long-term data on recurrence could not be evaluated and should be studied to determine the role of robotic surgery in VHR and recurrence rates.
