1 · What the graph read from it

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.

2 · The registry

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

Objectives: Cytoreductive surgery with heated intraperitoneal chemotherapy (CRS/HIPEC) requiring diaphragmatic stripping or resection may predispose to pleuropulmonary recurrence. This review was to assess the rates of pleuropulmonary recurrence after CRS/HIPEC for patients who had high-grade appendiceal neoplasm and meosthelioma. Methods: A retrospective review (September 1996-November 2021) at a single tertiary center identified 716 patients who underwent CRS/HIPEC with diaphragmatic intervention; 203 had high-grade appendiceal neoplasms and 63 had mesothelioma. Radiologic or pathologic evidence of pleuropulmonary recurrence was recorded. Time from CRS/HIPEC to chest recurrence was analyzed using Kaplan-Meier methods. Results: Twenty patients (12 appendiceal; 8 mesothelioma) developed pleuropulmonary recurrence. In the appendiceal cohort (mean age 51.5 years; median PCI 30), all 12 underwent bilateral diaphragm intervention (four with full-thickness resection) with CCR 0-1. Time to chest recurrence ranged from 0.3 to 82.8 months; half experienced early respiratory complications (e.g., pleural effusion, pneumothorax). In the mesothelioma cohort (mean age 44.9 years; median PCI 22.1), seven had bilateral stripping (two with resection) and one had unilateral stripping; CCR was 0-1. Recurrence occurred between 8.0 and 85.4 months (median ∼31.4 months); half had early respiratory compromise. No significant associations were observed between PCI, CCR, or extent of diaphragmatic intervention and recurrence risk, although ICU stay and CCR weakly correlated with recurrence in mesothelioma. Conclusions: Pleuropulmonary recurrence following CRS/HIPEC with diaphragm intervention is rare (2.7 %), with early recurrences suggesting occult thoracic involvement. Bilateral diaphragm manipulation was common among those with recurrence.
