Continuous wound infiltration versus placebo following elective minimally invasive colorectal surgery (CIMICS): study protocol for a randomised controlled trial.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundEnhanced Recovery After Surgery (ERAS) programs emphasize multimodal analgesia to minimize opioid use and improve patient outcomes. Continuous wound infiltration (CWI) with local analgesic is a promising adjunct to multimodal analgesia. However, its benefits in minimally invasive procedures and ERAS-adherent care remain unknown. This trial investigates whether the addition of CWI to standard ERAS care improves postoperative recovery following minimally invasive colorectal surgery.
methodsIn this single-centre, blinded, randomised controlled trial, 192 eligible patients are randomised to receive either a CWI system with bupivacaine 0.125% (the interventional arm), or a placebo CWI with physiological saline (the control arm). All patients receive standardized ERAS perioperative care with multimodal analgesia. The primary outcome is the Quality of Recovery-15 score (QoR-15NL) on postoperative day 2. Secondary outcomes include QoR-15NL and pain scores (postoperative days 1-5), opioid consumption, length of hospital stay, key functional recovery milestones, and 90-day postoperative complications. DISCUSSION: This will be the first randomised controlled trial evaluating the effect of CWI within minimally invasive and ERAS-adherent colorectal surgery. The trial findings may improve evidence-based perioperative care guidelines and enhance postoperative multimodal analgesia.
