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

objectivesTo evaluate the comparative outcomes and clinical characteristics of simultaneous and staged colorectal and hepatic resections for colorectal cancer with synchronous hepatic metastases.

methodsWe conducted a systematic search of electronic information sources, and bibliographic reference lists. Perioperative morbidity and mortality, anastomotic leak, wound infection, bile leak, bleeding, intra-abdominal abscess, sub-phrenic abscess, reoperation, recurrence, 5-year overall survival, procedure time, and length of hospital stay were the evaluated outcome parameters. Combined overall effect sizes were calculated using random-effects model.

resultsWe identified 41 comparative studies reporting a total of 12,081 patients who underwent simultaneous (n = 5013) or staged (n = 7068) resections for colorectal cancer with synchronous hepatic metastases. There were significantly lower use of neoadjuvant chemotherapy (p = 0.003), higher right-sided colonic resections (p < 0.00001), and minor hepatic resections (p < 0.00001) in the simultaneous group. The simultaneous resection was associated with significantly lower rate of bleeding (OR 0.60, p = 0.03) and shorter length of hospital stay (MD - 5.40, p < 0.00001) compared to the staged resection. However, no significant difference was found in perioperative morbidity (OR1.04, p = 0.63), mortality (RD 0.00, p = 0.19), anastomotic leak (RD 0.01, p = 0.33), bile leak (OR 0.83, p = 0.50), wound infection (OR 1.17, p = 0.19), intra-abdominal abscess (RD 0.01, p = 0.26), sub-phrenic abscess (OR 1.26, p = 0.48), reoperation (OR 1.32, p = 0.18), recurrence (OR 1.33, p = 0.10), 5-year overall survival (OR 0.88, p = 0.19), or procedure time (MD - 23.64, p = 041) between two groups.

conclusionsDespite demonstrating nearly comparable outcomes, the best available evidence (level 2) regarding simultaneous and staged colorectal and hepatic resections for colorectal cancer with synchronous hepatic metastases is associated with major selection bias. It is time to conduct high-quality randomised studies with respect to burden and laterality of disease. We recommend the staged approach for complex cases.
