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

Background: Studies on the coronal plane alignment of the knee (CPAK) classification after high tibial osteotomy (HTO) are scarce. Purpose: To (1) clarify the distribution of the CPAK phenotype in patients who underwent HTO and (2) compare the clinical results according to the CPAK phenotypes. Study Design: Case Series; Level of evidence, 4. Methods: Overall, 171 knees of patients with HTO were retrospectively evaluated. The primary outcome was to investigate the serial changes in the CPAK preoperatively and 2 years postoperatively. The secondary outcome was to assess the subcategories of the knee injury and osteoarthritis outcome score (KOOS) and postoperative change of KOOS according to the CPAK. Results: The most common pre- and postoperative CPAK phenotype types were I (62%), II (22.8%), IV (8.8%), VI (36.7%), V (18.9%), and IX (13%). The distribution of preoperative CPAK significantly changed after HTO. KOOS subscales showed no significant differences according to the CPAK phenotypes. Conclusion: The most common pre- and postoperative CPAK phenotypes were I and VI. No significant differences in the KOOS subscales were observed according to CPAK phenotypes following HTO.
