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

objectivesPerioperative oral care was reported to decrease postoperative pneumonia after cancer resections. However, the effect remains controversial because previous studies were limited due to their small sample sizes and lack of strict control for patient backgrounds. The present study evaluated the association between perioperative oral care and postoperative pneumonia using high-dimensional propensity score (hd-PS) matching to adjust for confounding factors. MATERIALS AND

methodsUsing a Japanese health insurance claims database, we identified patients who underwent surgical treatment of cancer from April 2014 to March 2015. To compare outcomes (postoperative pneumonia and procedure-related complications) between patients with and without perioperative oral care, we performed hd-PS matching and conventional PS matching and chi-square test.

resultsWe identified 621 patients with oral care and 4374 patients without oral care. The occurrences of postoperative pneumonia were not significantly different between patients with and without oral care in the unmatched (2.9% vs. 3.2%), conventional PS-matched (2.9% vs. 2.9%), or hd-PS-matched (2.9% vs. 3.3%) groups. The occurrences of procedure-related complication were not significantly different between patients with and without oral care in the unmatched (23.8% vs. 24.5%), conventional PS-matched (23.8% vs. 26.4%), or hd-PS-matched (24.4% vs. 27.7%) groups.

conclusionsThere was no significant difference in postoperative pneumonia or procedure-related complications between patients with and without perioperative oral care. CLINICAL RELEVANCE: While maintaining optimal oral care in cancer patients is an important goal, the present study revealed no significant difference in postoperative outcomes. Further investigations would be needed to determine the effect of perioperative oral care.
