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

objectivePreoperative physiotherapy in patients receiving primary total knee arthroplasty (TKA) aims to relieve pain, delay surgery, and improve postoperative recovery. This study investigates the change in PROMs and pain after primary TKA between patients who received preoperative physiotherapy (P) and those who did not (NP).

designRegistry-based cohort study with data from an institutional registry. PATIENTS: 1,688 patients followed a standardized fast-track clinical pathway between August 2017 and January 2024 and were grouped in P or NP.

methodsPrimary outcome was KOOS-PS at 2 months and 1 year postoperatively. Secondary outcomes included pain, the Forgotten Joint Score, and EQ-5d-5L. Two anchor questions related to self-perceived knee function and willingness to have the surgery again at 12 months' follow-up were also evaluated.

resultsThe model estimate demonstrated no significant between-group difference in KOOS-PS at 2 months (1.12 points; p = 0.079) or 1-year follow-up (1.25 points; p = 0.097). Visual inspection of descriptive plots showed that NP patients had higher KOOS-PS, less pain, and better joint score and quality of life at all time points. At 12 months' follow-up, both groups had similar responses to the anchor questions.

conclusionAfter adjustment for baseline differences, no between-group differences in postoperative self-reported physical function were observed; consistently lower scores in the physiotherapy group may reflect systematic preoperative differences between groups.
