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 aimed to compare the safety and effectiveness of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in patients aged 60 years old or older.

methodsThe available literature was searched for eligible studies up to November 2019. The meta-analysis was performed by the RevMan 5.3 software.

resultsThis meta-analysis involved nineteen studies. The rates of early and late complications in RYGB were much higher than those in SG. More specifically, within 30 days after surgeries, leak, urinary tract infection, obstruction, and death occurred more often in the RYGB group. The above differences may lead to higher rates of hospital readmission and return to the operating room. RYGB was superior to SG in terms of remission of hypertension and the 1-year follow-up weight loss outcome, while there were no differences in terms of remission of type 2 diabetes (T2D) and obstructive sleep apnea (OSA) as well as weight loss outcomes during 2- and 3-year follow-up.

conclusionsSG was the preferable option to RYGB for patients aged 60 years old or older, as SG has been shown not inferior to RYGB in terms of effectiveness, while being safer than RYGB.
