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

introductionThe purpose of this study is to determine which patient factors predict two-year postoperative met expectations in a cohort of patients undergoing knee surgery. Additionally, this study aims to measure the association between met expectations and postoperative outcomes.

methods319 patients undergoing knee surgery at one institution were studied. Patients completed patient-reported outcome questionnaires prior to surgery and again two years postoperatively. Preoperative Expectations and postoperative Met Expectations were measured using the Musculoskeletal Outcomes and Data Evaluation Management System (MODEMS) Expectations domain.

resultsThe mean Met Expectations score was significantly lower than the preoperative Expectations Score. Worse two-year Met Expectations were associated with older age, higher BMI, greater comorbidities, more previous surgeries, black race, unemployment, lower income, government insurance, Worker's Compensation, smoking, and no injury prior to surgery. Greater Met Expectations were correlated with better scores on all two-year outcome measures as well as greater improvement on most outcome measures. Race, insurance status, function, mental health, and knee pain were found to be independent predictors of Met Expectations.

conclusionThis study identified multiple patient factors and outcome measures that were associated with Met Expectations two years after knee surgery.
