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

Negative pressure injury is one of the auxiliary methods of treating diabetes foot ulcers. It has been shown to be superior to conventional techniques in randomized controlled trials (RCTs). Nevertheless, the results of observational research are still scarce. A systematic review of RCTs and observations was carried out to evaluate the effectiveness and security of negative pressure wound therapy (NPWT) treatment for diabetes foot ulcers. Three English e-databases have been found for NPWT research. The meta-analyses of the comparative studies provided point estimates of results. Intermediate results were given as median and binary values were given in the form of odds ratios (OR). Seventeen trials, 13 RCTs and four randomized, controlled trials were found in the survey. Of these, 831 were treated with NPWT, 834 were treated with standard therapy. A total of 14 studies have been conducted to investigate the influence of NPWT on the healing of diabetic foot ulcers(DFU). In the study, NPWT was shown to speed up the healing of the wound in DFU patients(OR, 2.57; 95% CI, 1.72, 3.85 p < 0.0001). A subgroup analysis showed that NPWT was associated with an acceleration of the wound healing rate in 10 RCT trials (OR, 2.48; 95% CI, 1.58, 3.89 p < 0.001). In the four nRCT trials, NPWT was also shown to speed up the healing of the wound(OR, 2.95; 95% CI, 1.03, 8.42 p = 0.04). In 11 studies, the influence of NPWT on amputations of diabetes mellitus (DM) foot ulcers was investigated. The results showed that NPWT was associated with a reduction in amputations (OR, 0.53; 95% CI, 0.37, 0.74 p = 0.0002).In a subgroup of RCT trials, nine RCT trials showed a reduction in amputations(OR, 0.61; 95% CI, 0.43, 0.87 p = 0.007). In both nRCT trials, NPWT also showed a reduction in amputations (OR, 0.03; 95% CI, 0.00, 0.24 p = 0.001). Generally speaking, NPWT can help to heal the wound and lower the risk of amputations in people with diabetes. The subgroup analysis showed similar results for the RCT and non-RCT trials. NPWT can be used to treat diabetes foot ulcers caused by diabetes.
