Neuroplastics approach to cerebrovascular bypass surgery: the way forward for centres with small to medium volume caseload.

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
purposeCerebral bypasses are technically challenging procedures essential in the neurosurgeon's armamentarium. Decreasing surgical indications leading to reduced caseload has resulted in less than ideal clinical outcomes, particularly in low to medium volume centres. We describe the neuroplastics approach to cerebral bypasses in the largest retrospective series to date and demonstrate how this approach has been able to smoothen the learning curve and achieve consistent outcomes approximating that of high-volume centres.
methodsA retrospective study was conducted. All patients who received a bypass were classified into those with bypasses performed using the neuroplastics approach (NP group) and those performed by solo neurosurgeons (Solo group). Technical outcomes and clinical outcomes were compared.
resultsThere were 19 patients in the NP group and 50 patients in the Solo group. There were 17 patients in the NP group with double-barrel bypasses and 2 with single-barrel bypasses (total of 36 direct anastomoses) and 45 patients of the Solo group with single-barrel bypasses and 5 patients with conversion to indirect bypasses. Patients in the Solo group were more likely to experience a postoperative stroke in the bypassed territory (Solo, 17.8%; NP, 0%; p = 0.008). Although not statistically significant, there was a difference in the proportion of patients with conversion to indirect bypass (Solo, 10.0%; NP, 0%), postoperative anastomotic bleed (Solo, 8.9%; NP, 0%), and long-term patency (Solo, 93.9%; NP, 100%). Patients in the NP group had a shorter median length of stay (NP, 3 [2 - 7] days; Solo, 6 [5 - 9] days; p = 0.005) and 1-year modified Rankin scale approached significance (NP, 0 [0 - 0]; Solo, 0 [0 - 2]).
conclusionOur experience supports the adoption of a neuroplastics approach to the training and execution of cerebrovascular bypasses in small to medium volume centres. This collaboration allowed us to deliver cerebral bypasses to indicated patients with excellent outcomes.
