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

The rate of drop in serum calcium post total thyroidectomy is a predictor of hypocalcemic symptoms in adults, after adjusting for other significant covariates.

introductionTest the hypothesis that rate of drop in calcium is a significant and independent predictor of post-operative hypocalcemic symptoms post total thyroidectomy.

methodsA retrospective chart review (electronic and hard copy) for 429 patients who underwent total thyroidectomy from January 2011 to December 2016. We collected information on demographics, clinical characteristics, information on surgical intervention, histopathology reports, clinical course, biochemistries, treatments and discharge instructions.

resultsSixty-one patients (14%) developed post-operative hypocalcemic symptoms. The rate of calcium drop, younger age, female gender, and lower body mass index, and the presence of parathyroid tissue in resected specimen all correlated significantly with the development of symptoms. The rate of drop in serum calcium and the post-operative serum calcium level remained the only significant predictors of symptom development, after adjustment for other significant co-variates. Using a receiver operating characteristics curve, a cutoff rate of calcium drop > 0.083 mg/dl/h, that is 1 mg/dl over 12 h, has a sensitivity of 71% and specificity of 73% for detecting hypocalcemic symptoms.

conclusionThe rate of drop of serum calcium post total thyroidectomy significantly and independently correlated with the development of hypocalcemic symptoms. Patients with a rate of drop < 1 mg/dl/12 h may be considered for earlier discharge and less aggressive management peri-operatively.
