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

purposeThe impact of regular exercises or physical activity (PA) on weight of bariatric patients need to be elucidated. We investigated PA levels, sedentary time (ST), and weight regain on these patients who were without regular medical follow-up before recruitment. Moreover, we investigated correlation and concordance between self-reported and objective measures in moderate-to-vigorous PA (MVPA) and ST. MATERIALS AND

methodsWe invited 132 patients previously subjected to a bariatric procedure to a medical appointment in our unit and proposed them to be volunteers. Ninety patients, aged 42 ± 8 years and BMI 32.9 ± 6.6 kg/m

resultsIn G5- group, PA and ST were similar between low and high RWR. In G5+ group, MVPA time, number of steps/day, percent of patients somewhat active, and 30-60 min/day of MVPA were statistically higher in those with low RWR. Of note, measures of MVPA < 30 min/day occurred more frequently in those with high RWR. MVPA and ST self-reported vs. objective measures were correlated (P < 0.001). Nevertheless, there was no concordance between these measures (P > 0.05).

conclusionsLow level of PA and longer ST occurred more frequently in those with high RWR and longer time since surgery. Although well-correlated, any concordance between IPAQ and accelerometer measures was noted.
