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
backgroundThe current study sought to investigate the safety of intraoperative and early postoperative continuous hyperthermic intraperitoneal perfusion (IEPCHIP) at different temperatures in a swine model of experimental distal gastrectomy with Billroth II reconstruction.
methodsThirty pigs were randomly divided into 5 groups. Two groups were used as the control groups (groups A1 and A2), and 3 groups were used as the perfusion groups (groups B, C and D). Pigs in group A1 received distal gastrectomy with Billroth II reconstruction only. Pigs in groups A2, B, C and D received the same surgery as group A1, followed by IEPCHIP at 37 ± 0.5°C, 42.5 ± 0.5°C, 43.5 ± 0.5°C or 44.5 ± 0.5°C, respectively. The perfusion time was assessed for each pig in group A2 as well as in the perfusion groups, and the perfusions were performed twice for each group. The first perfusion was conducted intraoperatively, and the second perfusion was initiated 1 day after surgery. Data concerning vital signs and hepatic and renal function were collected. Parameters concerning anastomotic healing, the pathology of the anastomotic tissue and abdominal adhesion were compared.
resultsThe vital signs and hepatic and renal functions of the pigs in groups A1, A2, B and C were not significantly affected by this procedure. In contrast, the vital signs and hepatic and renal functions of the pigs in group D were significantly affected. Compared to the pigs in groups A1, A2 or B, the anastomotic bursting pressure, breaking strength and hydroxyproline content in group C and D pigs were significantly lower. No significant differences were observed in these parameters between groups A1, A2 and B. Abdominal adhesion was more severe in group D pigs. Collagen deposition in group A1, A2 and B pigs was dense in the anastomosis, and inflammatory cell infiltration was observed in group D.
conclusionsIEPCHIP at 42.5 ± 0.5°C was safe and caused minimal impairments. However, anastomotic healing was affected by perfusion at 43.5 ± 0.5°C and 44.5 ± 0.5°C, and abdominal adhesion was most severe in the group D animals, which were perfused at 44.5 ± 0.5°C.
