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

backgroundHypersomatotropism (HST) is an increasingly recognized endocrinopathy in cats and is mostly described associated with diabetes mellitus (DM).

objectivesTo evaluate the efficacy and safety of transsphenoidal hypophysectomy in treating HST and DM in cats. ANIMALS: Sixty-eight client-owned cats with HST and DM treated by transsphenoidal hypophysectomy.

methodsRetrospective cohort study. Medical records were reviewed for glycemic control and serum insulin-like growth factor-1 (IGF-1) concentrations. Postoperative complications, death within 4 weeks, and proportion achieving diabetic remission were recorded. Survival times and DM-free intervals were calculated.

resultsFifty-eight cats (85.3%) were alive 4 weeks postoperatively with 10 (15%) postoperative deaths. Complications included hypoglycemia (n = 9), electrolyte imbalance (n = 9), and transient congestive heart failure (n = 5). Fifty-five cats (95% of 58 surviving cats [81% of all cats undergoing surgery]) had improved control of diabetes. Diabetic remission occurred in 41 cats (71% of 58 surviving cats [60% of all cats]) with insulin administration discontinued after a median of 9 days (range, 2-120). Postoperative 4-week serum IGF-1 concentration nadir was significantly lower in cats achieving diabetic remission (median 20 ng/mL [15-708] than those that did not (324 ng/mL [15-1955]; P = .03). All cats received long-term levothyroxine and hydrocortisone PO, alongside desmopressin (conjunctival) in 38 of 53 cats (72%). Recurrence of DM occurred in 5 of 41 cats (12%) after a median of 248 days (range, 84-1232). Median survival time of all cats was 853 days (range, 1-1740). CONCLUSIONS AND CLINICAL IMPORTANCE: Transsphenoidal hypophysectomy is an effective treatment for cats with HST and DM, with a long-term outcome that compares favorably to existing options.
