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

backgroundLaparoscopic total extraperitoneal (TEP) inguinal hernioplasty is significantly less painful than open repair, but it is not completely painless. Local anesthetics are thought to decrease postoperative pain when placed at the surgical site. We conducted a systematic review of randomized controlled trials (RCTs) to evaluate the efficacy of extraperitoneal bupivacaine treatment during laparoscopic inguinal hernia repair for the reduction of postoperative pain.

methodsWe conducted a systematic review and meta-analysis of RCTs that investigated the outcomes of extraperitoneal bupivacaine analgesia versus control in laparoscopic TEP hernia repair. Pain was assessed using a visual analog scale at 4-6 h and at 24 h following the surgery. The secondary outcomes included complications and analgesia consumption.

resultsWe reviewed eight trials that included a total of 373 patients. We found no difference between the groups in postoperative pain reduction following laparoscopic TEP inguinal hernia repair. The intensity of pain was not significantly different between the bupivacaine treatment group and the control group. The pooled mean differences in pain scores were -0.26 (95% CI -0.72 to 0.21) at 4-6 h and -0.47 (95% CI -1.24 to 0.29) at 24 h. No bupivacaine-related complications were reported.

conclusionExtraperitoneal bupivacaine treatment during laparoscopic TEP inguinal hernioplasty is not more efficacious for the reduction of postoperative pain than placebo.
