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

backgroundIn cervical cancer, para-aortic lymph nodes are common sites of metastasis. The purpose of the study was to evaluate the clinical benefits of prophylactic irradiation as postoperative therapy.

methodsA retrospective cohort study was conducted during 2001-2015 at a single institution. Patients with a high risk of para-aortic lymph nodes recurrence were eligible for this study, and we identified patients who had pelvic lymph node metastasis and underwent radical surgery and concurrent chemo-radiotherapy. As a result, 33 and 46 patients were included in the treatment (prophylactic irradiation) and non-treatment groups, respectively. Baseline differences between the two groups were adjusted with the inverse probability of treatment weighting using propensity scores composed of the independent variables including age, stage, tumor size, pathological findings, lymph node status, and pathological subtypes.

resultsIn the 68-month median follow-up period (range 6-178 months), 25 patients experienced recurrence, and 17 patients were dead. After adjustment with the inverse probability of treatment weighting, the recurrence rates tended to decrease in the treatment group, but there was no significant difference between the two groups [treatment vs. non-treatment, 29.4% and 44.3%, respectively; hazard ratio, 0.593 (95% CI 0.320-1.099); P = 0.097]. However, adjusted para-aortic lymph nodes recurrence rates were not significantly different [treatment vs. non-treatment, 7.8% and 11.4%, respectively; odds ratio, 0.660 (95% CI 0.187-2.322); P = 0.558]. Moreover, Kaplan-Meier curves showing post-recurrence survival revealed no significant difference between the two groups (P = 0.141).

conclusionsProphylactic para-aortic lymph nodes irradiation did not reduce the risk of recurrence.
