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

purposeSurgical site infection (SSI) after patella fracture surgery could be devastating and challenging. There is no large sample size study to investigate the prevalence and risk factors of it. The purpose of this study was to address this clinical issue.

methodsA total of 820 patients who underwent patella fracture surgery between October 2014 and December 2018, were included. Demographic data, fracture type, injury mechanism, pre-operative stay, surgery-related variables, and pre-operative laboratory indexes were obtained from a prospective database. The optimum cutoff value of surgery duration was detected by receiver operating characteristic analysis. Univariate analysis and multivariate analysis were performed to determine the risk factors.

resultsA total of 17 patients developed SSI after patella fracture surgery, indicating a prevalence of 2.1%, with 11 cases (1.3%) for superficial infection and six cases (0.8%) for deep infection. After adjustment of multiple variables, current smoking, (OR, 18.6, CI, 3.5-99.0); albumin < 35 g/L, (OR, 7.4, CI, 1.1-52.3); diabetes mellitus, (OR, 8.8, CI, 1.3-59.4) and surgery duration > 79.5 minutes, (OR, 13.2, CI, 1.5-117.3) were identified to be independent risk factors of SSI after patella fracture surgery (p < 0.05).

conclusionThe prevalence of SSI in patients with closed isolated patella fracture was 2.1%, with 1.3% for superficial and 0.8% for deep infection. We recommend individualized risk stratification and targeted interventions for patients with risk factors (current smoking, albumin < 35 g/L, diabetes mellitus, and surgery duration > 79.5 minutes).
