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
backgroundIntraoperative radiotherapy (IORT) can be applied for locally advanced tumors and expected or unavoidable R1 situations combined with surgical resection. The aim is to improve local tumor control and long-term survival. The indications are primary and recurrent intra-abdominal and retroperitoneal tumors. This study aimed to evaluate own data and experiences with IORT combined with surgical visceral resection.
methodsPatients who underwent IORT combined with abdominal tumor resection in the Department of General and Visceral Surgery at the University Medical Center Freiburg between January 2008 and December 2018 were included in this study. The results were retrospectively evaluated regarding short-term and long-term outcomes.
resultsThe most frequent indications for IORT were sarcoma followed by rectal and anal cancers. The median IORT dose used was 15 Gy (range 8-19 Gy). With a median comprehensive complication index (CCI) of 11.9, complications occurred in 24% of patients (Dindo-Clavien ≥ °III). The 90-day mortality was 0%. Especially in recurrent anal cancer the local control after 1 year was insufficient despite R0 resection.
conclusionIn this cohort of patients IORT could be applied with acceptable morbidity. Nevertheless, the indications and patient selection are critical factors for carrying out the treatment. The effect of IORT to improve local tumor control and long-term survival should be evaluated in further studies.
