Less pain and foreign body sensation after incisional hernia repair with partially absorbable mesh than with non-absorbable mesh: a retrospective sequential cohort study.

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
aimTo compare postoperative morbimortality and pain assessment in incisional hernia (IH) repair with partially absorbable or non-absorbable mesh types. MATERIALS &
methodsA monocentric retrospective two-arm comparative study between non-absorbable polyester (PET) (n = 108) and partially absorbable Poly-L-Lactic based (PLLA)- polypropylene (PP) mesh (n = 47) consecutive placement in IH repair. Its primary objective was postoperative morbimortality in patients with grade-II Clavien-Dindo Classification or higher during the first 90-day postoperative period. Secondary objectives were early hernia recurrences, type and rate of complications, chronic pain and long-term quality-of-life assessment using the Patient Reported Outcomes Measures questionnaire.
resultsBoth groups were comparable in terms of (i) Demographic characteristics (age 60 ± 12 (p = 0.19); Male (43.9%, p = 0.38), BMI 28.9 ± 4.7 kg/m² (p = 0.99)); (ii) Midline IH localization (76.8%, p = 0.65), Ventral Hernia Working Group (VHWG) grade-I (34.2%, p = 0.73) and grade-II (63.8%, p = 0.73); (iii) Surgical technique: mostly laparotomy (98.1%, p = 0.25) and retrorectus mesh placement (89%, p = 0.54). More Transversus Abdominis Release was observed in the PLLA/PP group (38.3% vs. 19.4% p = 0.04). Postoperative morbimortality was comparable between PLLA/PP and PET groups (10.6%vs13%;p = 0.7), without significant differences in SSO rates (14.9%vs16.7%;p = 0.8) and early recurrences (2%vs0%;p = 0.13). Lower foreign body sensation was observed in the PLLA/PP group (4.8%) compared to the PET group (20.3%, p = 0.024). In the prediction pain model, risk of chronic severe pain was higher in the PET group (21.6% vs. 3.9%, p = 0.023).
conclusionsPLLA/PP and PET mesh types have comparable safety. The predicted global risk of postoperative chronic pain was around 30%. However, the benefits of the PLLA/PP mesh could be correlated to its semi-absorbable nature.
