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 purpose of this study was to determine the natural temporal trends of serial thyroglobulin (Tg) among low/intermediate-risk PTC patients not receiving radioactive iodine (RAI) using TSH-stimulated Tg (Stim-Tg) and unstimulated highly sensitive Tg (u-hsTg). We prospectively analyzed serial Stim-Tg measurements after total thyroidectomy ± therapeutic central neck dissection among 121 consecutive low/intermediate-risk PTC patients who did not receive RAI, of whom 104 also had serial u-hsTg measurements available. Median follow-up was 6.5 years with Stim-Tg measurements commencing 3 months after surgery and u-hsTg commencing 1.8 years after surgery (when the assay became available). TSH stimulation was performed with 9-day T3 withdrawal, 22-day T4 withdrawal, or using recombinant human TSH (rhTSH). To account for within-patient correlations of repeated Tg measurements, temporal trends in Stim-Tg and u-hsTg were assessed using Generalized Estimating Equations. Stim-Tg models were adjusted for the method of TSH stimulation, whereas the u-hsTg models were adjusted for concurrent TSH level. Linear regression modeling was used to assess the trend in serial Stim-Tg and u-hsTg measurements as a function time from time of surgery throughout the duration of follow-up. The main outcome measured was the change in u-hsTg and Stim-Tg measurements over time. A total of 337 Stim-Tg (2.8/patient) and 602 u-hsTg (5.8/patient) measurements were analyzed. Among the 337 Stim-Tg measurements, Stim-Tg was assessed using rhTSH in 202 (60 %), T4 withdrawal in 41 (12 %), and T3 withdrawal in 94 (28 %) measurements. The overall mean ± 1SD for Stim-Tg and u-hsTg measured was 1.0 ± 1.2 and 0.2 ± 0.1 μg/L, respectively. When adjusted for method of TSH stimulation, serial Stim-Tg measurements did not significantly change over time (all p = NS). The estimated changes in Stim-Tg per year for rhTSH, T4 withdrawal, and T3 withdrawal were 0.01, -0.08, and 0.04 μg/L, respectively. Upon exclusion of 73 patients with an initial undetectable Stim-Tg (n = 48), serial Stim-Tg measurements did not change significantly over time (all p = NS). For these patients, the estimated changes in Stim-Tg per year for rhTSH, T4 withdrawal, and T3 withdrawal were -0.09, -0.10, and 0.01 μg/L, respectively. Serial u-hsTg measurements did not significantly change over time after adjusting for TSH level (p = NS). The estimated change in u-hsTg per year was -0.003 μg/L. No patients had any clinical or imaging evidence of a recurrence during the duration of their follow-up. Among low/intermediate-risk PTC patients not treated with RAI, serial post-surgical Stim-Tg and u-hsTg measurements do not change significantly over a median follow-up of 6.5 years.
