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

Laparoscopic cholecystectomy is associated with significant postoperative pain. The external oblique intercostal (EOI) block is a recently described superficial block that can be performed in the supine position and provides effective pain relief for upper abdominal surgeries. This case series aim to describe the use of the EOI block in providing analgesia following laparoscopic cholecystectomy. We reported three female patients, aged 62 to 71 years, who underwent laparoscopic cholecystectomy under general anaesthesia with an EOI block. None of the patients required opioids for intraoperative analgesia beyond induction. Postoperatively, all three patients reported only mild-to-moderate pain localized to the umbilical port site. Postoperative opioid consumption was minimal. No adverse effects or block-related complications were observed. The EOI block demonstrated promising efficacy in providing analgesia for laparoscopic cholecystectomy. Further studies are warranted to determine the effectiveness of the EOI block for a wider range of laparoscopic upper abdominal surgeries.
