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

backgroundOral cavity cancer is the most common cancer among rural India. There is a paucity of data for outcomes of operable oral cavity cancer from rural India. Use of maintenance metronomic may delay or avoid relapse.

aimTo evaluate outcomes of operable oral cavity carcinoma and evaluate impact of maintenance metronomic chemotherapy.

objectivesTo evaluate disease-free survival (DFS), overall survival (OS), and factors affecting the outcome in operable oral cavity cancer. MATERIALS AND

methodsData of patients diagnosed with oral cavity cancer registered between May 2008 and May 2014 were retrieved. Only those patients with operable oral cavity cancer and upfront definitive surgery were included in the study. Demographic profile, stage, tobacco consumption, adjuvant therapy, and pattern of failure were collected. Kaplan-Meir survival analysis was used to determine DFS and OS. Log-rank test was used to evaluate factors affecting outcome.

resultsMedian follow-up is 24 months. Out of 335 patients, 225 (67%) had advanced operable cancer with 42/225 (18%) and 183/225 (82%) as Stages III and IVA, respectively. Buccal mucosa was the most common subsite (178/335, 53%) followed by tongue (63/335, 19%). Ninety-two percent patients were addicted to smokeless tobacco, whereas 27% were smokers. Median DFS is 13 months with 2 years relative DFS 32%. Median OS is 30 months, with 2 years OS of 54%. Metronomic adjuvant oral chemotherapy was given in 130/225 (58%); Stage III and IVA patients with median of 14 months (3-18 months). Use of metronomic chemotherapy improved DFS (8 vs. 14 months, P = 0.22) and OS (14 vs. 26 months, P = 0.04).

conclusionOral cavity cancer is a major health care problem in rural India. Presentation at advanced stage leads to suboptimal outcomes. Benefit of metronomic maintenance chemotherapy in locally advanced oral cavity needs to be further evaluated prospectively.
