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
aimSuccessful anastomotic healing is essential in colorectal surgery and depends on adequate microcirculation at the resection site to prevent anastomotic leakage (AL). Traditionally, surgeons subjectively assess this. Laser speckle contrast imaging (LSCI) provides an objective, dye-free, and non-contact method for measuring the bowel end microcirculation that could perioperatively support the surgeon's assessment. This study aimed to determine the feasibility of LSCI and evaluate surgeons' subjective opinions on its potential to assist in surgical decision-making.
methodThis feasibility trial was conducted within the IDEAL framework as a non-interventional multicentre study. Patients undergoing elective right hemicolectomy were included. LSCI measurements were conducted twice perioperatively: before and after anastomosis formation. Surgeons were blinded to all measurements. Postoperatively, LSCI images and a questionnaire were presented to the surgeon asking whether these images, if presented perioperatively, would have influenced the selection of the optimal anastomotic site.
resultsHigh-quality LSCI measurements were obtained in all 20 patients operated on by 17 different surgeons, with clear and interpretable perfusion images captured without compromising sterility or extending operating time significantly. The device was non-invasive and added an average of 2 minutes to the total operation time. Fifteen of the 17 surgeons indicated that measures could have influenced surgical decision-making. In 50% of the cases, the surgeon reported a change in the resection site, by an average of 1.2 cm, based on LSCI images.
conclusionThis study demonstrated that LSCI effectively displays colonic perfusion in real-time without disrupting the surgical procedure. The potential clinical value of LSCI with additional visual feedback lies in assisting surgeons in selecting the most optimal anastomotic site, thereby potentially improving healing and surgical outcome.
