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

backgroundLate recurrence of renal cell carcinoma (RCC) is observed in some postoperative patients. In addition, some of these patients are lost to long-term postoperative follow-up. We reviewed the treatment results and prognosis of postoperative patients with RCC at Chiba University Hospital, with the aim of clarifying the proportion and background of patients lost to follow-up.

methodsThis retrospective study included 1176 RCC patients who underwent radical or/and partial nephrectomy. Overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and lost follow-up free survival (LFFS) were evaluated and the risk factors for LFFS identified.

resultsThe median RFS for stage II and II cases was 188.3 and 104.0 months, respectively. Even in stage I, recurrence was observed in about 20% of patients 20 years after surgery. The Kaplan-Meier curve for LFFS showed a linear descent over time, with 50% of patients lost to follow-up within 25 years. Older age (≥ 62 years), histological type (clear cell RCC), and no recurrence were significant risk factors for lost follow-up.

conclusionsLong-term follow-up is necessary after RCC surgery because late recurrence cases are not uncommon. We believe that lifelong follow-up with imaging studies is recommended for postoperative RCC patients. Early detection of recurrence in postoperative patients is a very important issue, and it may be worthwhile for improving the prognosis of postoperative patients to focus on patients lost to follow-up who may have been overlooked.
