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

purposeMultiple surgical techniques in minimally invasive total knee arthroplasty (TKA) are associated with clinical differences. However, whether patellar eversion impairs clinical outcomes remains controversial. We conducted a systematic review of randomized controlled trials (RCTs) to provide current understanding on this topic.

methodsA literature search of the PubMed, Embase, and Cochrane library databases was performed to identify RCTs comparing patellar eversion with patellar non-eversion (PN). Two authors independently selected the studies, assessed methodological quality, and extracted data.

resultsFive RCTs involving 379 knees were included. The results revealed no significant differences in functional scores, pain, quality of life, quadriceps strength, patellar height, alignment, or complication rate between patellar eversion and PN. Power analysis showed that the power of the individual study and meta-analysis ranged from 5.0 to 70.8%, with the exception of the power of alignment and patellar height in two of the individual studies, which was 100.0 and 99.9%, respectively.

conclusionsBased on the current evidence, patellar eversion during TKA could not definitely lead to inferior postoperative outcomes. Patellar eversion and patellar non-eversion could achieve similar clinical outcomes. LEVEL OF EVIDENCE: Systematic review and meta-analysis, Level I.
