Ambulatory inguinal hernia repair in Portugal - a multicenter prospective cohort study.
Observational study in Updates in surgery, 2025. 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
Ambulatory surgery is the recommended approach for elective inguinal hernia repair for most people. However, the relative use of this procedure in Portugal and its related outcomes are unknown. We aimed to assess complication rates in patients undergoing ambulatory and inpatient surgery. Prospective multicentric cohort study included consecutive patients undergoing elective inguinal hernia repair in mainland Portugal (October-December 2019). The primary outcome was the post-operative complication rate (any Clavien-Dindo grade) among patients undergoing ambulatory and inpatient surgery. A logistic regression analysis was performed to adjust for patient and disease-related co-variables. Eight hundred twenty-eight patients (89.1% of males) were included from thirty-three hospitals, of which seven hundred sixteen (86.4%) had unilateral hernias. Four hundred thirty-three (52.2%) were operated on as day cases and three hundred ninety-five (47.7%) with overnight stays. There were no significant differences in post-operative complication rate between patients undergoing ambulatory and overnight stay surgery, both in unadjusted (9.9% vs. 11.1%; p = 0.650) and adjusted (odds ratio: 1.08 [95% CI 0.66-1.76]) analyses. Ambulatory surgery was only performed in half of the patients, although this procedure is not associated with an increased risk of complications. These results should promote the expanded use of ambulatory surgery in patients eligible for elective inguinal hernia repair.
