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

purposeThis study sought to evaluate the complications and clinic outcome in radiographic parameters, pulmonary function, and nutritional status of halo-gravity traction (HGT) in treating severe spinal deformity.

methodsEmbase, PubMed, Cochrane, Web of Science databases were searched comprehensively for relevant studies from inception to February 2021, by using combined text and MeSH terms and English language restriction was used. The data, including radiographic parameters, pulmonary function (FVC %), and nutritional status (BMI) was extracted from included studies. All meta-analyses were conducted using random or fixed-effects models according the between-study heterogeneity, estimated with I

resultsFour hundred and forty-six studies were identified and twelve studies with a total of 372 patients were included in this review. Compared with pre-traction values, there were reduction in cobb angle of 28.12° [95% CI (22.18, 34.18)], decrease in thoracic kyphosis of 26.76°[95% CI (20.73, 32.78)], improvements in spine height[SMD = -0.89, 95% CI (- 1.56, - 0.21)] and in coronal balance[WMD = - 0.03, 95% CI (- 1.56, - 0.21), P = 0.84] with preoperative halo-gravity traction for severe spinal deformity patients. Besides, our pooled analysis showed the improvement in pulmonary function (FVC %) [WMD = - 9.56, 95% CI (- 1.56, - 0.21)] and increase in nutritional status (BMI) [WMD = - 0.50, 95% CI (- 1.56, - 0.21)].

conclusionPartial correction can be achieved by preoperative HGT, thereby reducing the difficulty of the operation and the risk of neurologic injury caused by excessive correction. Moreover, preoperative HGT can improve pulmonary function and nutritional status and, thus, increase patients' tolerance to surgery.
