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

backgroundThe aim of this study was to compare the influence of either general (GA) or local (LA) anesthesia on the postoperative neurocognitive outcome in patients undergoing carotid endarterectomy (CEA) in a randomized study. Therefore, we performed a subgroup analysis of the multicenter GALA study.

methodsA total of 40 patients were enrolled and randomized to receive either LA (n = 17) or GA (n = 23) anesthesia. The indication for intraoperative shunting was based on the intraoperative cognitive performance in the LA group and on the clinical experience of the surgeon in the GA group. Outcome measurements included patient performance on a neuropsychological Trail Making Test, evaluation of patients mood using the self-report inventory BSKE, and serum levels of the neurobiochemical marker S100beta. The data were analyzed for each variable using a t-test and were presented as the mean (SD). Differences in shunt frequency were analyzed performing a chi-squared test. Group differences in the Trail Making Test, BSKE evaluation, and S100beta concentrations were derived from the analyses of covariances with repeated measurements using preoperative values as covariates.

resultsCompared to baseline, the S100beta concentrations increased significantly in the GA group [0.086 (0.038) vs. 0.061 (0.024) microg/l; p < 0.001] before unclamping of the carotid artery, whereas there were no changes in the LA group [0.068 (0.024) microg/l, p = 0.09 vs. 0.061 (0.021) microg/l, p = 0.09). Furthermore, we detected significant group differences after surgical intervention (GA 0.087 (0.031) microg/l; LA 0.06 (0.021) microg/l; p = 0.006). The postoperative neurocognitive performance in the Trail Making Test decreased significantly in the GA group, whereas there were no significant changes in the LA group. The self-report inventory BSKE evaluation revealed no significant group differences.

conclusionsWe concluded that performing local anesthesia in patients undergoing CEA positively influenced early postoperative neurocognitive outcomes. Significant group differences in postoperative S100beta concentrations confirmed the beneficial effect of local anesthesia.
