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

purposeEffective postoperative analgesia is paramount in patients undergoing bariatric surgery, given their increased predisposition to narcotic-induced respiratory depression. Transversus abdominis plane (TAP) block has shown promise in the enhanced recovery pathway for several abdominal procedures. We performed a systematic review and meta-analysis to compare the effectiveness of TAP block in laparoscopic bariatric surgery. MATERIALS AND

methodsPubMed, EMBASE and Cochrane databases were searched for relevant articles from inception until June 2020. All randomized trials that compared TAP blocks versus none in laparoscopic bariatric procedures were included. The primary outcome was narcotic consumption at 24 h postoperatively, whilst secondary outcomes included postoperative pain scores at 24 h, time to ambulation, postoperative nausea and vomiting (PONV) and complication rates. Random effects models were used to calculate pooled effect size estimates.

resultsSeven randomized controlled trials were included, capturing 617 patients. There was high statistical heterogeneity across studies. On random effects analysis, there were no significant differences in narcotic consumption (MD -12.63 mg, 95% CI = -31.67 to 6.41, p = 0.19), pain scores (MD -0.71, 95% CI = -1.93 to 0.50, p = 0.25) or complications (RD = -0.00, 95% CI = -0.03 to 0.03, p = 0.87) between TAP and no TAP groups. However, TAP was associated with significantly less time to ambulation (MD -2.22 h, 95% CI = -3.89 to -0.56, p = 0.009) and PONV (OR = 0.13, 95% CI = 0.05 to 0.35, p < 0.0001).

conclusionsTAP in laparoscopic bariatric surgery is associated with significantly less PONV and time to ambulation, but similar complication rates, narcotic usage and postoperative pain at 24 h compared to no TAP.
