Impact of Phrenic Nerve Repair Using Intercostal Nerve Graft on Diaphragm Function after Thoracic Tumour Resection.

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
objectivesThis retrospective study investigated whether phrenic nerve repair with intercostal nerve graft affects postoperative diaphragmatic motion and respiratory function after thoracic tumour resection.
methodsWe included 11 consecutive patients (reconstruction group: n = 8; nonreconstruction group: n = 3) who underwent thoracic tumour resection with phrenic nerve removal between October 2023 and March 2025. In the reconstruction group, the intercostal and phrenic nerves were connected end-to-end using 5-0 or 6-0 Prolene sutures. Postoperative respiratory function, inspiratory/expiratory diaphragm movement distance (IEDD), and inspiratory/expiratory lung area (IEA) ratio on chest X-ray were measured using SYNAPSE VINCENT and compared between the 2 groups.
resultsNo significant differences in age, sex, and side of phrenic nerve resected were observed between the 2 groups. IEDD ≥10 mm within 1 month postoperatively was seen in 4 (50%) patients in the reconstruction group. Mean IEDD on X-ray was 19.8 mm vs 4.1 mm (P = .013) at 1-3 months and 19.8 mm vs 4.4 mm (P = .031) at 4-6 months for the reconstruction and nonreconstruction groups, respectively. Mean IEA ratios were 1.16 vs 1.04 (P = .026) at 1-3 months and 1.19 vs 1.05 (P = .031) at 4-6 months, respectively. Postoperative respiratory function showed higher %VC (78% vs 56%, P = .008) and %FEV1 (72% vs 45%, P < .001) in the reconstruction group at 4-6 months.
conclusionsPhrenic nerve repair with intercostal nerve graft mitigated diaphragmatic dysfunction and maintained postoperative respiratory function after phrenic nerve resection. CLINICAL REGISTRATION NUMBER: 2024 Eki-102.
