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

backgroundActual predictors of survival and recurrence for rectal cancer patients undergoing curative resection mostly come from pathological data of surgical specimen. Recently, novel blood biomarkers have been proposed as useful tools in cancer patient management, but few and conflicting data have been reported in rectal cancer. We evaluated the prognostic relevance of preoperative platelet-to-lymphocyte (P/L) ratio and neutrophil-to-lymphocyte (N/L) ratio on survival and recurrence in patients undergoing laparoscopic curative resection for rectal cancer.

methodsAll consecutive patients who referred for primary rectal disease to the Department of General Surgery in Cittadella (Italy) from June 2005 to September 2015 were retrospectively evaluated. Patients with metastatic disease at surgery were excluded. P/L and N/L ratios were calculated. For patients undergoing neoadjuvant chemo-radiotherapy, pre-treatment data were considered. Follow-up data were updated at December 2016.

resultsOne hundred fifty-two patients were included in the study, 49 (32%) received neoadjuvant chemo-radiotherapy. Both P/L and N/L ratios showed poor discriminative performance on 5-year OS and DFS. Time-dependent ROC curves showed no improvements in discriminative performance of P/L and N/L ratios when considering different time endpoints. Multivariable analysis identified CEA-rather than P/L or N/L ratios-as independent predictor of OS and DFS, adjusting for age, tumor stage, and postoperative morbidity.

conclusionNeither P/L nor N/L ratios were associated with survival after rectal cancer surgery. Further studies on large series might provide insights on the role of these inexpensive blood biomarkers in rectal cancer.
