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

aimTo investigate the potential oxidative stress in children with chronic constipation and to explore its mechanisms.

methodsSeventy children with chronic constipation and 70 age- and sex-matched healthy children were enrolled in a randomized controlled study. Plasma levels of vitamins C and E, activities of superoxide dismutase and catalase and lipoperoxide level in erythrocytes were determined by spectrophotometry.

resultsCompared with healthy children whose vitamin C, vitamin E, superoxide dismutase, catalase and lipoperoxide were 58.35+/-14.42 micromol/L, 27.15+/-6.55 micromol/L, 2 206+/-171 U/(g.Hb), 327.3+/-82.2 K/(g.Hb) and 19.18+/-4.27 nmol/(g.Hb) respectively, the levels of vitamin C, vitamin E, the activity of superoxide dismutase, and catalase in the children with chronic constipation significantly decreased [46.59+/-11.51 micromol/L, 20.65+/-4.80 micromol/L, 1943+/-147 U/(g.Hb) and 269.3+/-67.8 K/(g.Hb), respectively P<0.01], while the lipoperoxide significantly increased [25.22+/-5.01 nmol/(g.Hb), P<0.01]. With a prolonged course of disease, the levels of vitamin C, vitamin E, the activity of superoxide dismutase and catalase in the children with chronic constipation gradually decreased, while the level of lipoperoxide gradually increased.

conclusionChronic constipation can cause potential oxidative stress in children.
