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

backgroundSystemic vitamin C supplementation after wrist fracture has been suggested to reduce the incidence of complex regional pain syndrome (CRPS). This study aimed to evaluate the effect of regional vitamin C in Bier block in the early phase of fracture on CRPS occurrence following surgery for distal radius fractures.

methodsSeventy-four patients with isolated extra-articular distal radius fracture with the plan of fixation under Bier block were enrolled. Patients were assigned randomly into two groups: receiving either 500 mg vitamin C or sterile water as a Bier block adjuvant. Both groups received 500 mg of oral vitamin C for six weeks. The patients were evaluated for CRPS signs and symptoms at 2, 4, 6, and 12 weeks post-surgery.

resultsThe overall incidence of CRPS 12 weeks after surgery in the vitamin C group was significantly less than the controls (22.9% vs 45.5%, p = 0.04). Logistic regression analysis showed that the only significant contribution in predicting the incidence of CRPS came from the intervention variable (OR 0.26, CI95% 0.08-0.85; P = 0.027).

conclusionsThe findings suggest that adding vitamin C 500 mg to the local anesthetic in Bier block significantly reduces the incidence of CRPS following distal radius fractures.
