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 progressive muscle relaxation (PMR) + standard physiotherapy (PT) to standard PT during inpatient rehabilitation of total knee arthroplasty (TKA) patients in terms of post-operative outcomes. The hypothesis was that PMR + standard PT would lead to better pain, function, and neuromuscular outcomes than standard PT.

methodsA total of 106 patients were randomly allocated into PMR or standard rehabilitation (SR) groups. Both groups received standard PT during their hospital stay. PMR group additionally performed PMR exercise on post-operative days 1, 2, and 3. Patients were evaluated regarding pain intensity, functional outcomes, muscle strength, active range of motion, knee edema, anxiety, depression, and kinesiophobia.

resultsThere were no differences between groups at baseline (n.s.). During the inpatient period and at discharge, the PMR group had better results in terms of pain relief (p < 0.05), quadriceps strength (p = 0.001), kinesiophobia level (p = 0.011) compared to the SR group. No difference was detected between groups regarding other evaluation parameters during the inpatient period, at discharge, and third post-operative month (n.s.). The within-group analysis showed statistically significant differences over time in both groups in each variable (p < 0.05).

conclusionOur findings support that PMR therapy offers beneficial results in subjective and objective measures of TKA patients during the inpatient period. Therefore, PMR therapy could be implemented into the rehabilitation program of TKA patients to enhance their early recovery from various symptoms following TKA. LEVEL OF EVIDENCE: II.
