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

backgroundTransversus abdominus plane (TAP) blocks have become increasingly popular, due to a perceived reduction in post-operative pain following laparoscopic surgery. Their value following sleeve gastrectomy remains unclear.

objectivesTo perform a systematic review and meta-analysis of randomized clinical trials (RCTs) evaluating the efficacy of TAP block in patients undergoing laparoscopic sleeve gastrectomy.

settingIntegration of data from bariatric surgery units across the world.

methodsA systematic review was performed as per PRISMA guidelines. Meta-analysis was performed using Review Manager v5.4.

resultsEleven RCTs including 776 patients were included with 338 randomized to TAP block (50.0%). A non-significant equipoise was observed between groups for mean age, gender, body mass indices, and American Society of Anesthesiologists grades (all P > 0.050). At meta-analyses, patients receiving TAP block had significantly reduced post-operative visual analogue scores (VAS) at 0-60 min (mean difference (MD), - 1.23; 95% confidence interval (CI), - 1.87 to - 0.58; P < 0.001), 2 h (MD, - 1.78; 95% CI, - 3.28 to - 0.27; P < 0.001), 4 h (MD, - 1.00; 95% CI, - 1.24 to - 0.76; P < 0.001), 6 h (MD, - 1.58; 95% CI, - 2.46 to - 0.69; P < 0.001), 12 h (MD, - 1.13; 95% CI, - 1.80 to - 0.46; P = 0.001), and 24 h (MD, - 0.77; 95% CI - 1.42 to - 0.12; P < 0.001) respectively. At meta-analysis, a non-significant difference was observed for breakthrough analgesia consumption, time to rescue analgesia, post-operative nausea and vomiting, time to ambulation, length of stay, and post-operative complications. Patient satisfaction scores were significantly in favour of TAP block (MD, 0.88; 95% CI, 0.49-1.28; P < 0.001).

conclusionTAP block significantly reduced post-operative pain and improved patient satisfaction following sleeve gastrectomy. TAP block should be considered for patients undergoing this procedure, should expertise allow.
